Is there any plan to support window aggregation in Calcite Query Engine

[asdfgh19]

select  "deptno",
 rank() over (order by "deptno") as r
from "hr"."emps"

Calcite supports the above Sql, but Ignite's Calcite Query Engine does not support window aggregation syntax. Is there any plan to implement window aggregation in Calcite Query Engine.

I have early prototype implementation of window functions for Apache Ignite SE Calcite query engine. But I would like to get some information from the team:

• Is it already in development?
• Is there a IEP describing the team's vision?
• Do I have to provide a IEP for it?
• ASF Jira contains issue only for Ignite-3. Should I create my own issue for ISE?
