Rui Wang commented on CALCITE-3340: ----------------------------------- "TUMBLE_TABLE_FUNCTION" was a quick decision to skip some changes in validator. Ok, the next I will do is: 1. change "TUMBLE_TABLE_FUNCTION" back to "TUMBLE" (and more changes in validator) 2. correct formatting. 3. more javadoc/comments to explain the code. After this is done I will let you know. > Make TUMBLE be accepted as an operand for COLLECTION_TABLE(TABLE syntax) in > validator > ------------------------------------------------------------------------------------- > > Key: CALCITE-3340 > URL: https://issues.apache.org/jira/browse/CALCITE-3340 > Project: Calcite > Issue Type: Sub-task > Reporter: Rui Wang > Assignee: Rui Wang > Priority: Major > > For query: > SELECT * > FROM TABLE(TUMBLE( > TABLE ORDERS, > DESCRIPTOR(ROWTIME), > INTERVAL '10' MINUTE)) > (note reuse TUMBLE operator than use a new unresolved one) > Calcite validator will does a step to do registration and > "TABLE(TUMBLE(...))" will hit [1], where "TUMBLE(...)" will be passed to [2] > again but there is no matching Sqlkind handling for "TUMBLE" (note that > TUMBLE's node kind is TUMBLE). > It seems we should support TUMBLE in [2].
