There was a problem hiding this comment.
This seems like it is the API that would make sense, but I am still not 100% sure -- the Accumulator simply gets ArrayRef (not RecordBatch) so it currently doesn't know anything about the schema 🤔
Maybe we need to study how the existing built in aggregate functions that do support order by handle representing the ordering and follow the same model in UDAF

This is a proposed change to apache#9249, trying to illustrate the API changes needed. Note this does not compile (I haven't figure out how to pass sort exprs correctly yet) but I wanted to have some code to point at
