I like the idea that we leverage existing filter in AggregateExec for this usecase https://github.com/apache/datafusion/blob/c030bfe1e197fdbb385511a2e4fedf753f284d6f/datafusion/physical-plan/src/aggregates/mod.rs#L355-L356 I guess you can create `AggregateExec` with predicate that only non-nulls goes to array-agg, similar to the following syntax ``` select array_agg(column1) from table where column1 != NUll; ``` -- This is an automated message from the Apache Git Service.
