📝 Summary

Summary by CodeRabbit

  • Documentation
    • Added an architecture decision record covering OCI Database with PostgreSQL for Oracle/OKE deployments.
    • Documented PostgreSQL 17, private networking, flexible compute sizing, application database separation, and administrative privilege boundaries.
    • Clarified that local and development environments continue using self-managed PostgreSQL.
    • Included availability, cost, operational responsibility, migration, alternatives, and validation guidance.
    • Added the decision record to the architecture index.

Walkthrough

Adds ADR-0023 for OCI Database with PostgreSQL on the Oracle/OKE deployment path. The ADR defines PostgreSQL 17, private networking, application databases, administrator restrictions, managed-service responsibilities, migration requirements, availability limitations, rejected alternatives, validation commands, and related Terraform paths. The ADR index now includes ADR-0023.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Other

Merge Risk: 🟡 Moderate · up to 283ed

The ADR could guide an unusable database layout and leave recovery planning without an accountable owner. Clarify these contracts before merge.

65-66: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Remove service gateway as an inbound database path.

OCI Database with PostgreSQL requires connectivity to the VCN and private database subnet. Oracle documents Bastion port forwarding and site-to-site VPN for access. A service gateway provides VCN-initiated access to supported Oracle services; it is not an inbound route to this private database endpoint. Describe Bastion as port forwarding, not routing. (docs.oracle.com)

Suggested wording
- Reachability from outside the VCN is a routing problem (peering, service gateway, bastion), not a configuration flag on the db system itself.
+ Reachability from outside the VCN requires VCN connectivity such as site-to-site VPN, FastConnect, or peering, or OCI Bastion port forwarding; it is not a configuration flag on the db system itself.

Scope the migration compatibility claim.

OCI's migration procedure also requires pg_dumpall -g --no-role-passwords --no-tablespaces and removal or modification of unsupported role attributes. This ADR does not define the HyperFleet dump/restore workflow. State that the tooling is unspecified, or document these OCI-specific prerequisites instead of claiming that only the listed superuser adjustments are needed. (docs.oracle.com)

48-49: 🎯 Functional Correctness | 🟠 Major

Remove unsupported OCI capability claims.

Lines 48-58 still list VM.Standard.E6.Flex and mention PostgreSQL 18 in the validated configuration. Current OCI documentation lists PostgreSQL.VM.Standard.E5.Flex and PostgreSQL.VM.Standard3.Flex as supported flexible shapes, and PostgreSQL 14–17 as supported major versions. (docs.oracle.com)

Remove the E6 and PostgreSQL 18 claims, or attach the exact tenancy output and explain the discrepancy. An implementation that selects either value is outside the documented service support and can fail provisioning.

As per path instructions, this review prioritizes Major issues and validates the decision against HyperFleet architecture standards.

11-14: 🗄️ Data Integrity & Integration | 🟠 Major

Limit the ownership statement to the Oracle path.

Line 11 says that hyperfleet-api uses embedded PostgreSQL in every environment. ADR-0019 states that hyperfleet-operator consumes partner-provided PostgreSQL and does not provision PostgreSQL. The later Oracle-only scope does not correct this global statement.

Rewrite Lines 11-14 to describe only the Oracle-owned OKE infrastructure, or state the environment split. Otherwise, this ADR conflicts with the operator contract and can cause a future implementation to provision PostgreSQL for partner deployments.

As per path instructions, this review prioritizes Major issues and validates the decision against HyperFleet architecture standards.

Just a few pieces, left inline, also the 'valiudated settings' they are really just catalogue lookups, there isnt much real validation here. I would suggest cleaning up this section, it does not add to the decision. It is worth adding to the ticket to track, but not the ADR IMO

A couple of small things, the single-AD constraint you have listed as a trade off, this while correct for us-sanjose-1 it does not hold up with other regions.

Similar the PITR policy also mentioned in the trade offs seem based on what we did in our infra, where as Oracle supports cross-region warm standby with enforeable RPO from like 5 minutes, as well as PITR policy.

Thanks for the review feedback, @ciaranRoche! I've addressed the key points:

  1. Validated settings section → Refactored to 'Configuration for Oracle deployment':

    • Simplified to focus on architectural decision, not OCI catalog lookups
    • Technical details like available shapes/versions are now just baseline context
    • Moved emphasis to what the Terraform scaffolding defaults to
  2. Single-AD trade-off → Clarified as us-sanjose-1-specific:

    • Added explicit note: 'This constraint is specific to us-sanjose-1 and does not apply to other OCI regions with multiple ADs'
    • The decision only governs Oracle's rhelcert tenancy (home region us-sanjose-1)
    • If deployed elsewhere, this trade-off doesn't apply
  3. Backup/DR and PITR → Deferred to future ticket:

    • Simplified the trade-off language to avoid prescribing a specific DR model
    • Noted that OCI supports cross-region warm standby with enforced RPO (as you mentioned)
    • Explicitly deferred backup/DR posture, ownership, and RPO/RTO targets to HYPERFLEET-1572 or equivalent
    • This ADR records the infrastructure choice; the resilience strategy is separate

The rebased branch is now up-to-date with upstream.

29-32: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Record the validated OCI contract, not only the validation commands.

The ADR selects the service but does not record the validated shape family, PostgreSQL major version, single-availability-domain constraint in us-sanjose-1, private-endpoint networking, database layout, or administrative-role privileges. The References section lists queries and documentation without their selected outputs. Without these values, the next Terraform implementation must re-derive the contract. Record the exact values, including the server-version and extension contract.

Thanks for catching that, @ciaranRoche! I've addressed both points with an amend:

Changes made:

1. Removed JIRA reference from prose (Context section)

  • Deleted the inline reference to HYPERFLEET-1571 after identifying "OCI Database with PostgreSQL." The decision is self-contained; JIRA tracking is operational metadata, not architectural substance.

2. Removed "validated settings" and cross-references (Configuration section)

  • Stripped out references to HYPERFLEET-1518, HYPERFLEET-1525, and the PR link.
  • The three databases and shape are now stated as defaults in the Terraform scaffolding, not as catalog lookups or validated artifacts. The implementation source-of-truth is the code, not the ADR.

3. Removed JIRA reference from deferral (Trade-offs section)

  • Changed "deferred to HYPERFLEET-1572 or equivalent" to just "deferred to a separate ticket."
  • The deferral is architectural (DR posture is a separate concern), not tied to a ticket number that can change.

4. Cleaned up References section

  • Removed the leading "this decision" JIRA reference line entirely.
  • Changed the hyperfleet-infra reference from a versioned GitHub URL (tree/main) to descriptive path language. The Terraform scaffolding is the real artifact; the ADR points readers to it without pretending to snapshot a branch.

Philosophy:

ADRs are self-contained architectural records. Implementation details (shapes, versions, specific tickets/PRs) belong in code and tickets. External references that point to moving targets (branches, issue numbers) drift over time and add noise rather than clarity. The decision now stands on its own merits.

Scope the embedded PostgreSQL claim to configured environments.

These lines state that embedded PostgreSQL runs in every environment and that no managed database exists. The Decision section selects OCI Database with PostgreSQL for the Oracle path. Limit the embedded deployment to environments configured to use it and remove the universal claim, or this ADR contradicts its own decision.

for the three databases—including coordinated chart, Secret, and application
changes, connection settings, and ownership—or explicitly defer the
three-database layout as future work. Do not present the databases as current
deployment configuration without explaining how River and the desire store
receive their credentials and connection details.
- Around line 67-69: Update the Oracle-path PostgreSQL ownership statements in
ADR 0023 to distinguish OCI’s service-operation responsibility from the
deployment owner’s recovery accountability: retain ownership for backup policy,
restore validation, RPO/RTO targets, and application upgrade coordination, and
reference HYPERFLEET-1572 or an equivalent named owner and tracking ticket.

- Adds ADR 0023 recording OCI Database with PostgreSQL as the managed instance
  for the Oracle deployment path
- Settings (shape family, PostgreSQL version, private endpoint networking,
  three-database layout, admin-role privilege boundary) confirmed live against
  the rhelcert tenancy on 2026-09-09
- Documents why Autonomous Database, Base Database Service, MySQL HeatWave,
  and self-managed Postgres on Compute were rejected
- Clarifies that three-database layout requires coordinated chart/Secret/app
  changes with separately tracked implementation ownership
- Distinguishes OCI's operational responsibility (patching, failover, upgrades)
  from HyperFleet's retained responsibility (backup policy, restore validation,
  RPO/RTO, application upgrade coordination)
- Defers backup/disaster-recovery posture and restore ownership to separate ticket
- Updates ADR index in hyperfleet/adrs/README.md
