Vladimir Sitnikov created CALCITE-3656:
------------------------------------------
Summary: EnumerableNestedLoopJoin cost should account for cost of
inner restarts
Key: CALCITE-3656
URL: https://issues.apache.org/jira/browse/CALCITE-3656
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.21.0
Reporter: Vladimir Sitnikov
Assignee: Vladimir Sitnikov
EnumerableNestedLoopJoin uses makeCost(rowCount, 0, 0) which does not account
the efforts spent in restarting the nested loops.
For instance: select * from emp, dept where false produces 0 rows, however, it
still has non-trivial execution efforts.
