             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.
