Maksim Zhuravkov updated IGNITE-22204: -------------------------------------- Description: Patch IGNITE-16013 for AI-2 cannot be applied to AI-3, because that patch assumes that Sort's input always returns data from a single source. This assumption is not correct for the cases, when a query splits into multiple fragments. So {noformat} Sort(ordering=ord, offset=o, fetch=f) >Scan {noformat} into {noformat} Limit (offset=o, fetch=f) >Sort(ordering=ord, offset=o, fetch=f) >>Scan {noformat} Is not applicable. was: Patch IGNITE-16013 for AI-2 cannot be applied to AI-3, because that patch assumes that Sort's input always returns data from a single source.
