Summary: Pushdown Timestamp predicates to ORC reader
Key: IMPALA-10915
URL: https://issues.apache.org/jira/browse/IMPALA-10915
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Quanlong Huang
Assignee: Quanlong Huang
This is a follow-up task of predicate pushdown to the ORC reader (IMPALA-6505).
In IMPALA-6505 we skip pushing down predicates on Timestamp columns. As
[~csringhofer] pointed out in the review: https://gerrit.cloudera.org/c/17815,
we need to deal with corner cases like timezone conversion and timestamps
before 1970-01-01. Also add more tests for coverage.
