[jira] [Updated] (CALCITE-3340) Make TUMBLE be accepted as an
operand for COLLECTION_TABLE(TABLE syntax) in validator
[ https://issues.apache.org/jira/browse/CALCITE-3340?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rui Wang updated CALCITE-3340:
------------------------------
Description:
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]. The details of how to support it needs a bit more discussion and prototyping.
