URL: https://github.com/apache/iceberg/pull/14454
Description:
This PR adds support for configuring avro compression for Manifests and
ManifestLists using table properties.
Problem:
Despite configuration options existing for write.avro.compression-codec and
write.avro.compression-level, overriding these at the table properties level
does not actually change the compression level for writers. Many of the
code-paths to the manifest writers are hard-coded to use GZIP only.
Solution:
Ensure we are wiring through table properties to the ManifestLists writer
and Manifests writer
Testing
Added unit tests:
- TestManifestWriterVersions
- testDataFileManifestsCanUseAvroCompressionFromTableProperties
- testDeleteManifestsCanUseAvroCompressionFromTableProperties
- TestSnapshots:
- testManifestsHaveCorrectEncoding
- TestManifestListVersions:
- testOverrideManifestAvroCompression
