> > If we create filter version of GroupColumn that accumulate the filtered array into array builder for each column, output if the batch size reach target (i.e. 8192) > > Would this be a specialization of a filter of the aggregates like for `SELECT SUM(x) FROM ... HAVING SUM(x) > 5` ? Probably, but I think it has potential to reduce copied too https://github.com/apache/datafusion/issues/11628. It aggregates at the first place similar to coalescer's role and no gc required since we aggregate the value without necessary buffer copied. -- This is an automated message from the Apache Git Service.
