[jira] [Created] (CALCITE-3403) WindowReduceExpressionsRule does
not reuse RelMetadataQuery
Haisheng Yuan created CALCITE-3403:
--------------------------------------
Summary: WindowReduceExpressionsRule does not reuse RelMetadataQuery
Key: CALCITE-3403
URL: https://issues.apache.org/jira/browse/CALCITE-3403
Project: Calcite
Issue Type: Improvement
Reporter: Haisheng Yuan
It creates a new RelMetadataQuery instance, which is a fresh RelMetadataQuery without any data cache. We should get RelMetadataQuery from RelOptRuleCall to reuse cache as much as possible.
