[jira] [Created] (IMPALA-11141) Use exact data types in IN-list filter

Quanlong Huang created IMPALA-11141:
---------------------------------------

             Summary: Use exact data types in IN-list filter
                 Key: IMPALA-11141
                 URL: https://issues.apache.org/jira/browse/IMPALA-11141
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Quanlong Huang
            Assignee: Quanlong Huang


Currently, we use a std::unordered_set<int64_t> for all integer types (including DATE type). It's a waste of space for small data types like tinyint, smallint, int, etc. We'd better extends the base InListFilter class with different implementations for different data types.
