-----------------------------------
Hello Julian. I updated this JIRA title to limit the scope of a PR. Now the
scope is "Support Table Function TUMBLE in Planner".
As you suggested, I tried to work on a PR that add stream.iq and run it with
CoreQuidemTest. I realized it will require a Enumerable implementation, which
is large.
To make every contribution easy to review and with clear goal, I will suggest
we support table-value function TUMBLE in planner first to produce a usable
logical plan. I can create another JIRA to have a stream.iq test running that
build on top of this one.
Please let me know if you accept this proposal.

> Project: Calcite

> Labels: pull-request-available
> Time Spent: 2h 10m
> Remaining Estimate: 0h

> The goal of this JIRA is to generate a logical plan for the following query:
> {code:java}
> SELECT *
> FROM TABLE(TUMBLE(
> TABLE ORDERS,
> INTERVAL '10' MINUTE))
> {code}
> This SQL query does not have DESCRIPTOR included, which is being tracked and
> discussed by CALCITE-3339.
> I expect we should generate a logical plan from this query that is similar to
> the following:
> {code:java}
> LogicalProject(ROWTIME=[$0], ID=[$1], PRODUCT=[$2], UNITS=[$3], wstart=[$4],
> wend=[$5])
> LogicalTableFunctionScan(invocation=[TUMBLE($3, 60000:INTERVAL MINUTE)],
> rowType=[RecordType(TIMESTAMP(0) ROWTIME, INTEGER ID, VARCHAR(10) PRODUCT,
> INTEGER UNITS, TIMESTAMP(0) wstart, TIMESTAMP(0) wend)])
> LogicalProject(ROWTIME=[$0], ID=[$1], PRODUCT=[$2], UNITS=[$3])
> LogicalTableScan(table=[[ORINOCO, ORDERS]])
> {code}
