> DESCRIPTOR as a SQL operator in SqlStdOperatorTable
> ---------------------------------------------------
>
> Key: CALCITE-3339
> URL: https://issues.apache.org/jira/browse/CALCITE-3339
> Project: Calcite
> Issue Type: Sub-task
> Reporter: Rui Wang
> Assignee: Rui Wang
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.22.0
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> For query:
> SELECT *
> FROM TABLE(TUMBLE_TVF(
> TABLE ORDERS,
> DESCRIPTOR(ROWTIME),
> INTERVAL '10' MINUTE))
> TABLE ORDERS is converted to SqlPrefixOperator, but DESCRIPTOR(ROWTIME) has no mapping in SqlStdOperatorTable.
> There are two options:
> 1. There is a SqlColumnListConstructor which serves the same(similar) purpose to specific a list of column.
> 2. We create a new operator for DESCRIPTOR.
> Reuse existing code is always good so we can start from option one and see if it works.
