IMPALA-15101: Add Iceberg UUID primitive type
Introduce UUID as a new Impala primitive type with 16-byte inline tuple
slot storage. This patch adds only the foundational type-system, parser,
DDL analysis, and Iceberg schema mapping support needed to recognize
UUID columns. Query execution features (read path, predicates, casts,
aggregates) will follow in separate patches.
- Add TYPE_UUID to FE/BE/thrift
- Add UUID SQL keyword and DDL rules restricting UUID columns to Iceberg
tables
- Reject nested UUID types (ARRAY/MAP/STRUCT) in non-Iceberg CREATE/ALTER
TABLE
- Map Iceberg UUID schema fields to Impala Type.UUID for catalog/DESCRIBE
- Add minimal UuidCompatibility matrix entries required for catalog startup
- Defer UUID builtin registration until later patches add BE runtime support
- Add minimal BE inline-slot plumbing and uuid-util helpers/tests
Testing:
- FE tests:
- ParserTest for UUID type definitions in DDL and complex types
- AnalyzeDDLTest for Iceberg CREATE/ALTER TABLE with UUID columns
- Negative tests in AnalyzeExprsTest for UUID expressions
- BE tests:
- BE tests for UUID util functions
