keaton drebes updated CALCITE-4744:
-----------------------------------
Summary: Defer windowed aggregation function expansion to the planning
step (was: Add config for StandardConvertlet table to change if windowed
aggregation functions are decomposed)

> Key: CALCITE-4744
> URL: https://issues.apache.org/jira/browse/CALCITE-4744
> Project: Calcite
> Issue Type: New Feature
> Components: core
> Reporter: keaton drebes
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> I have a project that is working with windowed functions and we want to avoid
> the decomposition of certain aggregate functions (i.e. stddev) in the process
> of converting from an SqlNode to a RelNode. We have currently supported this
> by copying the entire StandardConvertlet table, and removing the convertlets
> responsible for this.
> It seems reasonable to control this behavior with a configuration for the
> StandardConvertlet table. Is this something that people would accept being
> merged into Calcite?
> I opened a draft PR to show the changes here:
> https://github.com/apache/calcite/pull/2496
