-------------------------------------
Summary: Calcite Planner: v1.40 of IntersectToDistinctRule throws
exception
Key: IMPALA-14419
URL: https://issues.apache.org/jira/browse/IMPALA-14419
Project: IMPALA
Issue Type: Sub-task
Reporter: Steve Carlin
The IntersectToDistinctRule is needed to change the LogicalIntersect RelNode
into a RelNode that Impala can understand. This Calcite v1.37 version of this
rule worked fine with Impala.
On upgrade to v1.40, the rule stopped working. This is because it adds a
COUNT() FILTER function which has issues that need further investigating.
Since the rule works fine for 1.37 and it was just an optimization that was
added, we can continue to use the 1.37 rule until the problem is fixed. A Jira
will be filed for enabling the 1.40 rule to work.
