validator (was: Make TUMBLE be accepted as an operand for
COLLECTION_TABLE(TABLE syntax) in validator)
> Make TUMBLE be accepted as an operand for "FROM TABLE()" 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
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
