Ramin Gharib updated FLINK-40486:
---------------------------------
Description:
Scope:
- UuidType in flink-table-common, backed by a fixed 16-byte value
- LogicalTypeRoot.UUID
- DataTypes.UUID() factory
- FlinkTypeFactory mapping UuidType <-> Calcite SqlTypeName.UUID
- LogicalTypeParser: recognize the UUID keyword -> UuidType
The SQL grammar already parses UUID as both a type keyword and a
UUID '...' literal via Calcite (Parser.jj:4899, 5980), so no sql-parser
change is needed. Calcite already provides SqlTypeName.UUID (CALCITE-6738),
so no Calcite bump. The UUID() function is unrelated and stays CHAR(36).
Verifying: unit tests for the type, DataTypes factory, the type-factory
round-trip, and LogicalTypeParser parsing "UUID".
was:
Add UUID as a first-class logical type.
