[GitHub] [calcite] rubenada opened a new pull request #1246: [CALCITE-2968] New AntiJoin relational expression (Work In Progress)

rubenada opened a new pull request #1246: [CALCITE-2968] New AntiJoin relational expression (Work In Progress)
URL: https://github.com/apache/calcite/pull/1246
 
 
   Jira ticket: https://issues.apache.org/jira/browse/CALCITE-2968
   
   - RelBuilder#antiJoin creates now a Join with type=ANTI (instead of a LogicalCorrelate type=ANTI, which was the only possibility so far)
   - AntiJoin must work in EnumerableConvention with all types of join condition: equi-join (via EnumerableHashJoin), and non equi-join (via EnumerableNestedLoopJoin)
   - AntiJoin can be correctly transformed into a Correlate (type ANTI) via JoinToCorrelateRule
