---------------------------------------
Summary: Add In filter to druid adapter.
Key: CALCITE-1655
URL: https://issues.apache.org/jira/browse/CALCITE-1655
Project: Calcite
Issue Type: Bug
Components: druid
Reporter: slim bouguerra
Assignee: Julian Hyde
The druid calcite adapter throw an exception when an IN filter is used.
This happens only in hive because in calcite project the IN filter is
transformed to OR automatically.
Since this rule does not kick in HIVE and it is better to use the native IN
filter from druid instead having huge number of OR clauses i will send a patch
that adds the IN filter.
