Purpose
Keep index manifests written by the current Paimon version readable by older Paimon releases.
Changes
IndexManifestEntrySerializerat version 1 instead of writing version 2.sourceMetaas an optional schema field while preserving the legacy five-field global-index schema.Root cause
The serializer version is persisted in every index manifest entry. Older Paimon versions only accept version 1, so entries written with version 2 are rejected before schema evolution can handle the optional field.
Tests
mvn -pl paimon-core -DwildcardSuites=none -Dtest=IndexManifestEntrySerializerTest,IndexManifestFileHandlerTest test
