+<span class="sd">    Cloud Spanner Instance Admin API</span>
+
+<span class="sd">    The Cloud Spanner Instance Admin API can be used to create, delete,</span>
+<span class="sd">    modify and list instances. Instances are dedicated Cloud Spanner serving</span>
+<span class="sd">    and storage resources to be used by Cloud Spanner databases.</span>
+
+<span class="sd">    Each instance has a \&quot;configuration\&quot;, which dictates where the</span>
+<span class="sd">    serving resources for the Cloud Spanner instance are located (e.g.,</span>
+<span class="sd">    US-central, Europe). Configurations are created by Google based on</span>
+<span class="sd">    resource availability.</span>
+
+<span class="sd">    Cloud Spanner billing is based on the instances that exist and their</span>
+<span class="sd">    sizes. After an instance exists, there are no additional</span>
+<span class="sd">    per-database or per-operation charges for use of the instance</span>
+<span class="sd">    (though there may be additional network bandwidth charges).</span>
+<span class="sd">    Instances offer isolation: problems with databases in one instance</span>
+<span class="sd">    will not affect other instances. However, within an instance</span>
+<span class="sd">    databases can affect each other. For example, if one database in an</span>
+<span class="sd">    instance receives a lot of requests and consumes most of the</span>
+<span class="sd">    instance resources, fewer resources are available for other</span>
+<span class="sd">    databases in that instance, and their performance may suffer.</span>

-Client
-======
-
-To use the API, the :class:`~google.cloud.spanner.client.Client`
-class defines a high-level interface which handles authorization
-and creating other objects:
-
-.. code:: python
-
-    from google.cloud.spanner.client import Client
-    client = Client()
-
-Long-lived Defaults
--------------------
-
-When creating a :class:`~google.cloud.spanner.client.Client`, the
-``user_agent`` and ``timeout_seconds`` arguments have sensible
-defaults
-(:data:`~google.cloud.spanner.client.DEFAULT_USER_AGENT` and
-:data:`~google.cloud.spanner.client.DEFAULT_TIMEOUT_SECONDS`).
-However, you may over-ride them and these will be used throughout all API
-requests made with the ``client`` you create.
-
-Configuration
--------------
-
-- For an overview of authentication in ``google.cloud-python``,
-  see :doc:`/core/auth`.
-
-- In addition to any authentication configuration, you can also set the
-  :envvar:`GCLOUD_PROJECT` environment variable for the Google Cloud Console
-  project you'd like to interact with. If your code is running in Google App
-  Engine or Google Compute Engine the project will be detected automatically.
-  (Setting this environment variable is not required, you may instead pass the
-  ``project`` explicitly when constructing a
-  :class:`~google.cloud.storage.client.Client`).
-
-- After configuring your environment, create a
-  :class:`~google.cloud.storage.client.Client`
-
-  .. code::
-
-     >>> from google.cloud import spanner
-     >>> client = spanner.Client()
-
-  or pass in ``credentials`` and ``project`` explicitly
-
-  .. code::
-
-     >>> from google.cloud import spanner
-     >>> client = spanner.Client(project='my-project', credentials=creds)
-
-.. tip::
-
-    Be sure to use the **Project ID**, not the **Project Number**.
-
-
-Next Step
----------
-
-After a :class:`~google.cloud.spanner.client.Client`, the next
-highest-level object is an :class:`~google.cloud.spanner.instance.Instance`.
-You'll need one before you can interact with databases.
-
-Next, learn about the :doc:`instance-usage`.

+
+Transactions
+============
+
+Each session can have at most one active transaction at a time. After
+the active transaction is completed, the session can immediately be
+re-used for the next transaction. It is not necessary to create a new
+session for each transaction.
+
+Transaction Modes
+=================
+
+Cloud Spanner supports two transaction modes:
+
+1. Locking read-write. This type of transaction is the only way to write
+   data into Cloud Spanner. These transactions rely on pessimistic
+   locking and, if necessary, two-phase commit. Locking read-write
+   transactions may abort, requiring the application to retry.
+
+2. Snapshot read-only. This transaction type provides guaranteed
+   consistency across several reads, but does not allow writes. Snapshot
+   read-only transactions can be configured to read at timestamps in the
+   past. Snapshot read-only transactions do not need to be committed.
+
+For transactions that only read, snapshot read-only transactions provide
+simpler semantics and are almost always faster. In particular, read-only
+transactions do not take locks, so they do not conflict with read-write
+transactions. As a consequence of not taking locks, they also do not
+abort, so retry loops are not needed.
+
+Transactions may only read/write data in a single database. They may,
+however, read/write data in different tables within that database.
+
+Locking Read-Write Transactions
+-------------------------------
+
+Locking transactions may be used to atomically read-modify-write data
+anywhere in a database. This type of transaction is externally
+consistent.
+
+Clients should attempt to minimize the amount of time a transaction is
+active. Faster transactions commit with higher probability and cause
+less contention. Cloud Spanner attempts to keep read locks active as
+long as the transaction continues to do reads, and the transaction has
+not been terminated by [Commit][google.spanner.v1.Spanner.Commit] or
+[Rollback][google.spanner.v1.Spanner.Rollback]. Long periods of
+inactivity at the client may cause Cloud Spanner to release a
+transaction's locks and abort it.
+
+Reads performed within a transaction acquire locks on the data being
+read. Writes can only be done at commit time, after all reads have been
+completed. Conceptually, a read-write transaction consists of zero or
+more reads or SQL queries followed by
+[Commit][google.spanner.v1.Spanner.Commit]. At any time before
+[Commit][google.spanner.v1.Spanner.Commit], the client can send a
+[Rollback][google.spanner.v1.Spanner.Rollback] request to abort the
+transaction.
+
+Semantics
+~~~~~~~~~
+
+Cloud Spanner can commit the transaction if all read locks it acquired
+are still valid at commit time, and it is able to acquire write locks
+for all writes. Cloud Spanner can abort the transaction for any reason.
+If a commit attempt returns ``ABORTED``, Cloud Spanner guarantees that
+the transaction has not modified any user data in Cloud Spanner.
+
+Unless the transaction commits, Cloud Spanner makes no guarantees about
+how long the transaction's locks were held for. It is an error to use
+Cloud Spanner locks for any sort of mutual exclusion other than between
+Cloud Spanner transactions themselves.
+
+Retrying Aborted Transactions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+When a transaction aborts, the application can choose to retry the whole
+transaction again. To maximize the chances of successfully committing
+the retry, the client should execute the retry in the same session as
+the original attempt. The original session's lock priority increases
+with each consecutive abort, meaning that each attempt has a slightly
+better chance of success than the previous.
+
+Under some circumstances (e.g., many transactions attempting to modify
+the same row(s)), a transaction can abort many times in a short period
+before successfully committing. Thus, it is not a good idea to cap the
+number of retries a transaction can attempt; instead, it is better to
+limit the total amount of wall time spent retrying.
+
+Idle Transactions
+~~~~~~~~~~~~~~~~~
+
+A transaction is considered idle if it has no outstanding reads or SQL
+queries and has not started a read or SQL query within the last 10
+seconds. Idle transactions can be aborted by Cloud Spanner so that they
+don't hold on to locks indefinitely. In that case, the commit will fail
+with error ``ABORTED``.
+
+If this behavior is undesirable, periodically executing a simple SQL
+query in the transaction (e.g., ``SELECT 1``) prevents the transaction
+from becoming idle.
+
+Snapshot Read-Only Transactions
+-------------------------------
+
+Snapshot read-only transactions provides a simpler method than locking
+read-write transactions for doing several consistent reads. However,
+this type of transaction does not support writes.
+
+Snapshot transactions do not take locks. Instead, they work by choosing
+a Cloud Spanner timestamp, then executing all reads at that timestamp.
+Since they do not acquire locks, they do not block concurrent read-write
+transactions.
+
+Unlike locking read-write transactions, snapshot read-only transactions
+never abort. They can fail if the chosen read timestamp is garbage
+collected; however, the default garbage collection policy is generous
+enough that most applications do not need to worry about this in
+practice.
+
+Snapshot read-only transactions do not need to call
+[Commit][google.spanner.v1.Spanner.Commit] or
+[Rollback][google.spanner.v1.Spanner.Rollback] (and in fact are not
+permitted to do so).
+
+To execute a snapshot transaction, the client specifies a timestamp
+bound, which tells Cloud Spanner how to choose a read timestamp.
+
+The types of timestamp bound are:
+
+-  Strong (the default).
+-  Bounded staleness.
+-  Exact staleness.
+
+If the Cloud Spanner database to be read is geographically distributed,
+stale read-only transactions can execute more quickly than strong or
+read-write transaction, because they are able to execute far from the
+leader replica.
+
+Each type of timestamp bound is discussed in detail below.
+
+Strong
+~~~~~~
+
+Strong reads are guaranteed to see the effects of all transactions that
+have committed before the start of the read. Furthermore, all rows
+yielded by a single read are consistent with each other -- if any part
+of the read observes a transaction, all parts of the read see the
+transaction.
+
+Strong reads are not repeatable: two consecutive strong read-only
+transactions might return inconsistent results if there are concurrent
+writes. If consistency across reads is required, the reads should be
+executed within a transaction or at an exact read timestamp.
+
+See
+[TransactionOptions.ReadOnly.strong][google.spanner.v1.TransactionOptions.ReadOnly.strong].
+
+Exact Staleness
+~~~~~~~~~~~~~~~
+
+These timestamp bounds execute reads at a user-specified timestamp.
+Reads at a timestamp are guaranteed to see a consistent prefix of the
+global transaction history: they observe modifications done by all
+transactions with a commit timestamp <= the read timestamp, and observe
+none of the modifications done by transactions with a larger commit
+timestamp. They will block until all conflicting transactions that may
+be assigned commit timestamps <= the read timestamp have finished.
+
+The timestamp can either be expressed as an absolute Cloud Spanner
+commit timestamp or a staleness relative to the current time.
+
+These modes do not require a "negotiation phase" to pick a timestamp. As
+a result, they execute slightly faster than the equivalent boundedly
+stale concurrency modes. On the other hand, boundedly stale reads
+usually return fresher results.
+
+See
+[TransactionOptions.ReadOnly.read\_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.read\_timestamp]
+and
+[TransactionOptions.ReadOnly.exact\_staleness][google.spanner.v1.TransactionOptions.ReadOnly.exact\_staleness].
+
+Bounded Staleness
+~~~~~~~~~~~~~~~~~
+
+Bounded staleness modes allow Cloud Spanner to pick the read timestamp,
+subject to a user-provided staleness bound. Cloud Spanner chooses the
+newest timestamp within the staleness bound that allows execution of the
+reads at the closest available replica without blocking.
+
+All rows yielded are consistent with each other -- if any part of the
+read observes a transaction, all parts of the read see the transaction.
+Boundedly stale reads are not repeatable: two stale reads, even if they
+use the same staleness bound, can execute at different timestamps and
+thus return inconsistent results.
+
+Boundedly stale reads execute in two phases: the first phase negotiates
+a timestamp among all replicas needed to serve the read. In the second
+phase, reads are executed at the negotiated timestamp.
+
+As a result of the two phase execution, bounded staleness reads are
+usually a little slower than comparable exact staleness reads. However,
+they are typically able to return fresher results, and are more likely
+to execute at the closest replica.
+
+Because the timestamp negotiation requires up-front knowledge of which
+rows will be read, it can only be used with single-use read-only
+transactions.
+
+See
+[TransactionOptions.ReadOnly.max\_staleness][google.spanner.v1.TransactionOptions.ReadOnly.max\_staleness]
+and
+[TransactionOptions.ReadOnly.min\_read\_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.min\_read\_timestamp].
+
+Old Read Timestamps and Garbage Collection
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Cloud Spanner continuously garbage collects deleted and overwritten data
+in the background to reclaim storage space. This process is known as
+"version GC". By default, version GC reclaims versions after they are
+one hour old. Because of this, Cloud Spanner cannot perform reads at
+read timestamps more than one hour in the past. This restriction also
+applies to in-progress reads and/or SQL queries whose timestamp become
+too old while executing. Reads and SQL queries with too-old read
+timestamps fail with the error ``FAILED_PRECONDITION``.

+Instantiating a Client
+----------------------
+
+To use the API, the :class:`~google.cloud.spanner.client.Client`
+class defines a high-level interface which handles authorization
+and creating other objects:

+.. code:: python
+
+    from google.cloud import spanner

+
+Long-lived Defaults
+-------------------
+
+When creating a :class:`~google.cloud.spanner.client.Client`, the
+``user_agent`` and ``timeout_seconds`` arguments have sensible
+defaults
+(:data:`~google.cloud.spanner.client.DEFAULT_USER_AGENT` and
+:data:`~google.cloud.spanner.client.DEFAULT_TIMEOUT_SECONDS`).
+However, you may over-ride them and these will be used throughout all API
+requests made with the ``client`` you create.
+
+Configuration
+-------------
+
+- For an overview of authentication in ``google.cloud-python``,
+  see :doc:`/core/auth`.
+
+- In addition to any authentication configuration, you can also set the
+  :envvar:`GCLOUD_PROJECT` environment variable for the Google Cloud Console
+  project you'd like to interact with. If your code is running in Google App
+  Engine or Google Compute Engine the project will be detected automatically.
+  (Setting this environment variable is not required, you may instead pass the
+  ``project`` explicitly when constructing a
+  :class:`~google.cloud.storage.client.Client`).
+
+- After configuring your environment, create a
+  :class:`~google.cloud.storage.client.Client`
+
+  .. code::
+
+     >>> from google.cloud import spanner
+     >>> client = spanner.Client()
+
+  or pass in ``credentials`` and ``project`` explicitly

+<dd><p>Cloud Spanner Instance Admin API</p>
+<p>The Cloud Spanner Instance Admin API can be used to create, delete,
+modify and list instances. Instances are dedicated Cloud Spanner serving
+and storage resources to be used by Cloud Spanner databases.</p>
+<p>Each instance has a “configuration”, which dictates where the
+serving resources for the Cloud Spanner instance are located (e.g.,
+US-central, Europe). Configurations are created by Google based on
+resource availability.</p>
+<p>Cloud Spanner billing is based on the instances that exist and their
+sizes. After an instance exists, there are no additional
+per-database or per-operation charges for use of the instance
+(though there may be additional network bandwidth charges).
+Instances offer isolation: problems with databases in one instance
+will not affect other instances. However, within an instance
+databases can affect each other. For example, if one database in an
+instance receives a lot of requests and consumes most of the
+instance resources, fewer resources are available for other
+databases in that instance, and their performance may suffer.</p>

+<dd><p>Cloud Labels are a flexible and lightweight mechanism for
+organizing cloud resources into groups that reflect a
+customer’s organizational needs and deployment strategies.
+Cloud Labels can be used to filter collections of resources.
+They can be used to control how resource metrics are
+aggregated. And they can be used as arguments to policy
+management rules (e.g. route, firewall, load balancing, etc.).
+-  Label keys must be between 1 and 63 characters long and
+must conform    to the following regular expression:
+<code class="docutils literal"><span class="pre">[a-z]([-a-z0-9]*[a-z0-9])?</span></code>. -  Label values must be
+between 0 and 63 characters long and must    conform to the
+regular expression <code class="docutils literal"><span class="pre">([a-z]([-a-z0-9]*[a-z0-9])?)?</span></code>. -  No
+more than 64 labels can be associated with a given resource.
+See <a class="reference external" href="https://goo.gl/xmQnxf">https://goo.gl/xmQnxf</a> for more information on and examples
+of labels.  If you plan to use labels in your own code, please
+note that additional characters may be allowed in the future.
+And so you are advised to use an internal label
+representation, such as JSON, which doesn’t rely upon specific
+characters being disallowed. For example, representing labels
+as the string: name + “*” + value would prove problematic if
+we were to allow “*” in a future release.</p>

+<p>Each session can have at most one active transaction at a time. After
+the active transaction is completed, the session can immediately be
+re-used for the next transaction. It is not necessary to create a new
+session for each transaction.</p>
+</div>
+<div class="section" id="transaction-modes">
+<h1>Transaction Modes<a class="headerlink" href="#transaction-modes" title="Permalink to this headline">#</a></h1>
+<p>Cloud Spanner supports two transaction modes:</p>
+<ol class="arabic simple">
+<li>Locking read-write. This type of transaction is the only way to write
+data into Cloud Spanner. These transactions rely on pessimistic
+locking and, if necessary, two-phase commit. Locking read-write
+transactions may abort, requiring the application to retry.</li>
+<li>Snapshot read-only. This transaction type provides guaranteed
+consistency across several reads, but does not allow writes. Snapshot
+read-only transactions can be configured to read at timestamps in the
+past. Snapshot read-only transactions do not need to be committed.</li>
+</ol>
+<p>For transactions that only read, snapshot read-only transactions provide
+simpler semantics and are almost always faster. In particular, read-only
+transactions do not take locks, so they do not conflict with read-write
+transactions. As a consequence of not taking locks, they also do not
+abort, so retry loops are not needed.</p>
+<p>Transactions may only read/write data in a single database. They may,
+however, read/write data in different tables within that database.</p>
+<div class="section" id="locking-read-write-transactions">
+<h2>Locking Read-Write Transactions<a class="headerlink" href="#locking-read-write-transactions" title="Permalink to this headline">#</a></h2>
+<p>Locking transactions may be used to atomically read-modify-write data
+anywhere in a database. This type of transaction is externally
+consistent.</p>
+<p>Clients should attempt to minimize the amount of time a transaction is
+active. Faster transactions commit with higher probability and cause
+less contention. Cloud Spanner attempts to keep read locks active as
+long as the transaction continues to do reads, and the transaction has
+not been terminated by [Commit][google.spanner.v1.Spanner.Commit] or
+[Rollback][google.spanner.v1.Spanner.Rollback]. Long periods of
+inactivity at the client may cause Cloud Spanner to release a
+transaction’s locks and abort it.</p>
+<p>Reads performed within a transaction acquire locks on the data being
+read. Writes can only be done at commit time, after all reads have been
+completed. Conceptually, a read-write transaction consists of zero or
+more reads or SQL queries followed by
+[Commit][google.spanner.v1.Spanner.Commit]. At any time before
+[Commit][google.spanner.v1.Spanner.Commit], the client can send a
+[Rollback][google.spanner.v1.Spanner.Rollback] request to abort the
+transaction.</p>
+<div class="section" id="semantics">
+<h3>Semantics<a class="headerlink" href="#semantics" title="Permalink to this headline">#</a></h3>
+<p>Cloud Spanner can commit the transaction if all read locks it acquired
+are still valid at commit time, and it is able to acquire write locks
+for all writes. Cloud Spanner can abort the transaction for any reason.
+If a commit attempt returns <code class="docutils literal"><span class="pre">ABORTED</span></code>, Cloud Spanner guarantees that
+the transaction has not modified any user data in Cloud Spanner.</p>
+<p>Unless the transaction commits, Cloud Spanner makes no guarantees about
+how long the transaction’s locks were held for. It is an error to use
+Cloud Spanner locks for any sort of mutual exclusion other than between
+Cloud Spanner transactions themselves.</p>
+</div>
+<div class="section" id="retrying-aborted-transactions">
+<h3>Retrying Aborted Transactions<a class="headerlink" href="#retrying-aborted-transactions" title="Permalink to this headline">#</a></h3>
+<p>When a transaction aborts, the application can choose to retry the whole
+transaction again. To maximize the chances of successfully committing
+the retry, the client should execute the retry in the same session as
+the original attempt. The original session’s lock priority increases
+with each consecutive abort, meaning that each attempt has a slightly
+better chance of success than the previous.</p>
+<p>Under some circumstances (e.g., many transactions attempting to modify
+the same row(s)), a transaction can abort many times in a short period
+before successfully committing. Thus, it is not a good idea to cap the
+number of retries a transaction can attempt; instead, it is better to
+limit the total amount of wall time spent retrying.</p>
+</div>
+<div class="section" id="idle-transactions">
+<h3>Idle Transactions<a class="headerlink" href="#idle-transactions" title="Permalink to this headline">#</a></h3>
+<p>A transaction is considered idle if it has no outstanding reads or SQL
+queries and has not started a read or SQL query within the last 10
+seconds. Idle transactions can be aborted by Cloud Spanner so that they
+don’t hold on to locks indefinitely. In that case, the commit will fail
+with error <code class="docutils literal"><span class="pre">ABORTED</span></code>.</p>
+<p>If this behavior is undesirable, periodically executing a simple SQL
+query in the transaction (e.g., <code class="docutils literal"><span class="pre">SELECT</span> <span class="pre">1</span></code>) prevents the transaction
+from becoming idle.</p>
+</div>
+</div>
+<div class="section" id="snapshot-read-only-transactions">
+<h2>Snapshot Read-Only Transactions<a class="headerlink" href="#snapshot-read-only-transactions" title="Permalink to this headline">#</a></h2>
+<p>Snapshot read-only transactions provides a simpler method than locking
+read-write transactions for doing several consistent reads. However,
+this type of transaction does not support writes.</p>
+<p>Snapshot transactions do not take locks. Instead, they work by choosing
+a Cloud Spanner timestamp, then executing all reads at that timestamp.
+Since they do not acquire locks, they do not block concurrent read-write
+transactions.</p>
+<p>Unlike locking read-write transactions, snapshot read-only transactions
+never abort. They can fail if the chosen read timestamp is garbage
+collected; however, the default garbage collection policy is generous
+enough that most applications do not need to worry about this in
+practice.</p>
+<p>Snapshot read-only transactions do not need to call
+[Commit][google.spanner.v1.Spanner.Commit] or
+[Rollback][google.spanner.v1.Spanner.Rollback] (and in fact are not
+permitted to do so).</p>
+<p>To execute a snapshot transaction, the client specifies a timestamp
+bound, which tells Cloud Spanner how to choose a read timestamp.</p>
+<p>The types of timestamp bound are:</p>
+<ul class="simple">
+<li>Strong (the default).</li>
+<li>Bounded staleness.</li>
+<li>Exact staleness.</li>
+</ul>
+<p>If the Cloud Spanner database to be read is geographically distributed,
+stale read-only transactions can execute more quickly than strong or
+read-write transaction, because they are able to execute far from the
+leader replica.</p>
+<p>Each type of timestamp bound is discussed in detail below.</p>
+<div class="section" id="strong">
+<h3>Strong<a class="headerlink" href="#strong" title="Permalink to this headline">#</a></h3>
+<p>Strong reads are guaranteed to see the effects of all transactions that
+have committed before the start of the read. Furthermore, all rows
+yielded by a single read are consistent with each other – if any part
+of the read observes a transaction, all parts of the read see the
+transaction.</p>
+<p>Strong reads are not repeatable: two consecutive strong read-only
+transactions might return inconsistent results if there are concurrent
+writes. If consistency across reads is required, the reads should be
+executed within a transaction or at an exact read timestamp.</p>
+<p>See
+[TransactionOptions.ReadOnly.strong][google.spanner.v1.TransactionOptions.ReadOnly.strong].</p>
+</div>
+<div class="section" id="exact-staleness">
+<h3>Exact Staleness<a class="headerlink" href="#exact-staleness" title="Permalink to this headline">#</a></h3>
+<p>These timestamp bounds execute reads at a user-specified timestamp.
+Reads at a timestamp are guaranteed to see a consistent prefix of the
+global transaction history: they observe modifications done by all
+transactions with a commit timestamp &lt;= the read timestamp, and observe
+none of the modifications done by transactions with a larger commit
+timestamp. They will block until all conflicting transactions that may
+be assigned commit timestamps &lt;= the read timestamp have finished.</p>
+<p>The timestamp can either be expressed as an absolute Cloud Spanner
+commit timestamp or a staleness relative to the current time.</p>
+<p>These modes do not require a “negotiation phase” to pick a timestamp. As
+a result, they execute slightly faster than the equivalent boundedly
+stale concurrency modes. On the other hand, boundedly stale reads
+usually return fresher results.</p>
+<p>See
+[TransactionOptions.ReadOnly.read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.read_timestamp]
+and
+[TransactionOptions.ReadOnly.exact_staleness][google.spanner.v1.TransactionOptions.ReadOnly.exact_staleness].</p>
+</div>
+<div class="section" id="bounded-staleness">
+<h3>Bounded Staleness<a class="headerlink" href="#bounded-staleness" title="Permalink to this headline">#</a></h3>
+<p>Bounded staleness modes allow Cloud Spanner to pick the read timestamp,
+subject to a user-provided staleness bound. Cloud Spanner chooses the
+newest timestamp within the staleness bound that allows execution of the
+reads at the closest available replica without blocking.</p>
+<p>All rows yielded are consistent with each other – if any part of the
+read observes a transaction, all parts of the read see the transaction.
+Boundedly stale reads are not repeatable: two stale reads, even if they
+use the same staleness bound, can execute at different timestamps and
+thus return inconsistent results.</p>
+<p>Boundedly stale reads execute in two phases: the first phase negotiates
+a timestamp among all replicas needed to serve the read. In the second
+phase, reads are executed at the negotiated timestamp.</p>
+<p>As a result of the two phase execution, bounded staleness reads are
+usually a little slower than comparable exact staleness reads. However,
+they are typically able to return fresher results, and are more likely
+to execute at the closest replica.</p>
+<p>Because the timestamp negotiation requires up-front knowledge of which
+rows will be read, it can only be used with single-use read-only
+transactions.</p>
+<p>See
+[TransactionOptions.ReadOnly.max_staleness][google.spanner.v1.TransactionOptions.ReadOnly.max_staleness]
+and
+[TransactionOptions.ReadOnly.min_read_timestamp][google.spanner.v1.TransactionOptions.ReadOnly.min_read_timestamp].</p>

+<div class="section" id="old-read-timestamps-and-garbage-collection">
+<h3>Old Read Timestamps and Garbage Collection<a class="headerlink" href="#old-read-timestamps-and-garbage-collection" title="Permalink to this headline">#</a></h3>
+<p>Cloud Spanner continuously garbage collects deleted and overwritten data
+in the background to reclaim storage space. This process is known as
+“version GC”. By default, version GC reclaims versions after they are
+one hour old. Because of this, Cloud Spanner cannot perform reads at
+read timestamps more than one hour in the past. This restriction also
+applies to in-progress reads and/or SQL queries whose timestamp become
+too old while executing. Reads and SQL queries with too-old read
+timestamps fail with the error <code class="docutils literal"><span class="pre">FAILED_PRECONDITION</span></code>.</p>

+<p>A range has a start key and an end key. These keys can be open or
+closed, indicating if the range includes rows with that key.</p>
+<p>Keys are represented by lists, where the ith value in the list
+corresponds to the ith component of the table or index primary key.
+Individual values are encoded as described
+[here][google.spanner.v1.TypeCode].</p>
+<p>For example, consider the following table definition:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">CREATE</span> <span class="n">TABLE</span> <span class="n">UserEvents</span> <span class="p">(</span>
+  <span class="n">UserName</span> <span class="n">STRING</span><span class="p">(</span><span class="n">MAX</span><span class="p">),</span>
+  <span class="n">EventDate</span> <span class="n">STRING</span><span class="p">(</span><span class="mi">10</span><span class="p">)</span>
+<span class="p">)</span> <span class="n">PRIMARY</span> <span class="n">KEY</span><span class="p">(</span><span class="n">UserName</span><span class="p">,</span> <span class="n">EventDate</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The following keys name rows in this table:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">,</span> <span class="s2">&quot;2014-09-23&quot;</span><span class="p">]</span>
+<span class="p">[</span><span class="s2">&quot;Alfred&quot;</span><span class="p">,</span> <span class="s2">&quot;2015-06-12&quot;</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>Since the <code class="docutils literal"><span class="pre">UserEvents</span></code> table’s <code class="docutils literal"><span class="pre">PRIMARY</span> <span class="pre">KEY</span></code> clause names two
+columns, each <code class="docutils literal"><span class="pre">UserEvents</span></code> key has two elements; the first is the
+<code class="docutils literal"><span class="pre">UserName</span></code>, and the second is the <code class="docutils literal"><span class="pre">EventDate</span></code>.</p>
+<p>Key ranges with multiple components are interpreted lexicographically by
+component using the table or index key’s declared sort order. For
+example, the following range returns all events for user <code class="docutils literal"><span class="pre">&quot;Bob&quot;</span></code> that
+occurred in the year 2015:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">,</span> <span class="s2">&quot;2015-01-01&quot;</span><span class="p">]</span>
+<span class="s2">&quot;end_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">,</span> <span class="s2">&quot;2015-12-31&quot;</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>Start and end keys can omit trailing key components. This affects the
+inclusion and exclusion of rows that exactly match the provided key
+components: if the key is closed, then rows that exactly match the
+provided components are included; if the key is open, then rows that
+exactly match are not included.</p>
+<p>For example, the following range includes all events for <code class="docutils literal"><span class="pre">&quot;Bob&quot;</span></code> that
+occurred during and after the year 2000:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">,</span> <span class="s2">&quot;2000-01-01&quot;</span><span class="p">]</span>
+<span class="s2">&quot;end_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>The next example retrieves all events for <code class="docutils literal"><span class="pre">&quot;Bob&quot;</span></code>:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">]</span>
+<span class="s2">&quot;end_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>To retrieve events before the year 2000:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">]</span>
+<span class="s2">&quot;end_open&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;Bob&quot;</span><span class="p">,</span> <span class="s2">&quot;2000-01-01&quot;</span><span class="p">]</span>
+</pre></div>
+</div>
+<p>The following range includes all rows in the table:</p>
+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[]</span>
+<span class="s2">&quot;end_closed&quot;</span><span class="p">:</span> <span class="p">[]</span>
+</pre></div>
+</div>
+<p>This range returns all users whose <code class="docutils literal"><span class="pre">UserName</span></code> begins with any

+<div class="highlight-default"><div class="highlight"><pre><span></span><span class="s2">&quot;start_closed&quot;</span><span class="p">:</span> <span class="p">[</span><span class="s2">&quot;A&quot;</span><span class="p">]</span>

+.PartialResultSet.chunked_value] field. Two or more chunked

+concatenate the (field name, field value) pairs. If a    field
+name is duplicated, then apply these rules recursively to

+# Strings are concatenated.     “foo”, “bar” =&gt; “foobar”
+# Lists of non-strings are concatenated.     [2, 3], [4] =&gt;
+[2, 3, 4]      # Lists are concatenated, but the last and

+[“a”, “b”], [“c”, “d”] =&gt; [“a”, “bc”, “d”]      # Lists are
+concatenated, but the last and first elements are merged     #
+because they are lists. Recursively, the last and first
+elements     # of the inner lists are merged because they are
+strings.     [“a”, [“b”, “c”]], [[“d”], “e”] =&gt; [“a”, [“b”,
+“cd”], “e”]      # Non-overlapping object fields are combined.
+{“a”: “1”}, {“b”: “2”} =&gt; {“a”: “1”, “b”: 2”}      #
