mxm opened a new pull request, #17018: URL: https://github.com/apache/iceberg/pull/17018
The PK index keys rows by (spec id, equality values), so a delete only matches data written under the same spec. However, according to the Iceberg table spec, while a partitioned delete applies only within its own spec, an unpartitioned equality delete must apply across every spec. This change drops the spec id from the key, so all rows with the same equality values co-locate on one shard. We scope at resolve time instead: RESOLVE_DELETE carries the delete's spec id, or a GLOBAL_DELETE_SPEC_ID when the delete is unpartitioned. The index deletes a row only when the delete is global or the row's spec id matches. DVPosition already carries each row's spec id, so no extra row state is needed. -- This is an automated message from the Apache Git Service.
