Description
Adds support for Iceberg format version 3 tables: creation, v2→v3 upgrade, and inserts.
Unsupported v3 features now fail fast with
NOT_SUPPORTED:Changes:
IcebergUtil.java: AddMAX_FORMAT_VERSION_FOR_ROW_LEVEL_OPERATIONS=2,MAX_SUPPORTED_FORMAT_VERSION=3IcebergAbstractMetadata.java: AddvalidateTableForPresto()for v3 feature validation; updatebeginMerge/Delete/Update/Insertto enforce version limitsIcebergSplitSource.java: Reject PUFFIN format delete filesRewriteDataFilesProcedure.java: Block OPTIMIZE on v3 tablesMotivation and Context
Mirrors Trino PR #27786. Enables incremental v3 adoption while preventing spec violations from unsupported features.
Impact
"format-version" = '3'NOT_SUPPORTEDTest Plan
