Julian Hyde updated CALCITE-978: -------------------------------- Labels: drill (was: ) > Make ReduceExpressionsRule extensible to transform false filter in > schema-on-read case > --------------------------------------------------------------------------------------- > > Key: CALCITE-978 > URL: https://issues.apache.org/jira/browse/CALCITE-978 > Project: Calcite > Issue Type: Bug > Reporter: Jinfeng Ni > Assignee: Julian Hyde > Labels: drill > > This comes from a commit in Drill's forked Calcite > (https://github.com/dremio/calcite/commit/a29f007f4f4017368b6f41bf8c3aba4490a1cee8). > ReduceExpressionRule will transform a false filter into VALUES with empty > input. This only works in the case of schema-aware scenario. In > schema-on-read scenario like Drill, VALUES would not provide the schema type > at the planning time; schema has to be propagate during execution time. > We should allow ReduceExpressionRule extensible so that different behavior > would be allowed to handle false filter in both schema-aware case and > schema-on-read case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
