Summary
Revert #742 until Apache
datafusion-iceberguses aniceberg-rustrevision containing FileScanTask serialization support.#742 aligned our Iceberg dependencies with upstream's older
665c64erevision, dropping that support. Distributed scans panic inFileScanTaskWorkUnit::serialized()withSerialization not implemented for this field, andexecutes_with_estimated_scan_tasksthen hangs. Reproduced on the merge commit.This is an exact revert: restore the previous
4d83bc7dependency pins and local predicate conversion implementation, without changing task-count or transport behavior.Fixes #748.
Validation
