I can't reply to this inline somehow, but > This looks a little strange to me too. Is concat_arrays actually doing anything here, and if so, wouldn't it do it for the case that selfDestruct is False too? 1) Yes, it's copying each column in the record batch into its own allocation, as explained in the latest commit. I couldn't find a more explicit way in Arrow to copy a column out of a record batch. 2) Yes, I can try to thread through a parameter, though I think it's harmless in this case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
