IMPALA-14783: Add time travel support for SHOW FILES on Iceberg tables
Extends SHOW FILES to accept FOR SYSTEM_TIME AS OF and FOR SYSTEM_VERSION
AS OF clauses for Iceberg tables.
Reuses the existing opt_asof grammar rule shared with SELECT time-travel.
Syntax:
SHOW FILES IN <table>
[FOR SYSTEM_VERSION AS OF <integer_literal>]
[FOR SYSTEM_TIME AS OF <timestamp_expr>]
[PARTITION (<filter>)]
The time-travel clause is placed before the optional PARTITION clause.
Both can be combined to filter filesby snapshot and partition
simultaneously.
Testing:
- ParserTest: positive cases for new syntax and negative cases with
invalid snapshot IDs.
- AnalyzeDDLTest: analysis-level validation with snapshot IDs,
timestamps and partition filters. Negative cases with non-Iceberg tables.
- E2E tests with dynamic snapshot IDs and timestamps;
covers version-based, timestamp-based, now(), partition filter combos,
SELECT consistency checks, and negative cases
