---------------------------------------
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.
