JingsongLi opened a new pull request, #9808:
URL: https://github.com/apache/paimon/pull/9808
### Purpose
Non-partitioned tables with fixed or postponed buckets currently reject
`manifest-sort.enabled`, although bucket IDs provide a useful sort key. Allow
these tables to sort manifest entries by bucket, followed by entry kind and
file name, without requiring a partition field.
Share sort eligibility between compaction and dry-run, conservatively treat
missing bucket statistics as overlapping ranges, and retain the existing Data
Evolution RowID sorting behavior. Update the configuration descriptions and
generated documentation.
### Tests
Added regression tests for fixed/postponed buckets, full and minor
compaction, ADD/DELETE cancellation with identical file names in different
buckets, missing bucket statistics, touching/overlapping bucket ranges in
dry-run, and schema validation.
```bash
mvn -o -pl paimon-core -am -DwildcardSuites=none -DfailIfNoTests=false \
-Dtest=NoPartitionManifestFileMetaTest,SchemaValidationTest,ManifestFileMetaTest,ManifestFileMergerTest,ManifestEntryRunMergeTest,ManifestRewriteCleanupTest
\
test
```
Validated on JDK 8 with 189 tests passed and one pre-existing disabled test
skipped. Checkstyle, Spotless, and Enforcer passed without the fast-build
profile. The local macOS run supplied Byte Buddy as a startup Java agent
because runtime attachment was unavailable. The updated generated configuration
descriptions were also checked against `CoreOptions`.
