rubenada opened a new pull request #1269: [CALCITE-3109] Improvements on algebraic operators to express recursive queries (RepeatUnion & TableSpool)
URL: https://github.com/apache/calcite/pull/1269
 
 
   Jira ticket: [CALCITE-3109](https://issues.apache.org/jira/browse/CALCITE-3109) 
   Pending details from [CALCITE-2812](https://issues.apache.org/jira/browse/CALCITE-2812) to make the RepeatUnion and TableSpool more consistent:
   
   TableSpool:
   - Replace `String tableName` with `RelOptTable table`.
   
   RepeatUnion:
   - Rename `maxRep` as `iterationLimit`. Change this field to allow all integer values, and treat all negative values as "no limit".
   - EnumerableDefaults#repeatUnionAll: make close method idempotent
