[jira] [Created] (IMPALA-10915) Pushdown Timestamp predicates to ORC reader

Quanlong Huang created IMPALA-10915:
---------------------------------------

             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.
