Change subject: IMPALA-12815: Support timestamp for scan predicates for
external data source table.
......................................................................
IMPALA-12815: Support timestamp for scan predicates
for external data source table.
Binary SCAN predicates involving timestamp literals are pushed down
to remote Database. The current logic assumes ISO 8601 (SQL standard)
format for timestamp literals - 'yyyy-mm-dd hh:mm:ss.ms'
Testing:
- Added custom cluster tests for timestamp predicates with operators:
'=', '>', '<', '>=', '<=', '!=', 'BETWEEN' for postgres, mysql
and remote impala.
- Added coverage for timestamp with/without time in the timestamp
- Added coverage for timestamp with/without milliseconds in timestamp.
- Added Planner tests to check predicate pushdown for date/timestamp
literals, date/timestamp functions and CASTs
