@ad1happy2go Not sure if this is really something blocked by spark sql parser, as an example Delta Lake supports schema evolution in MERGE INTO (both for partial updates as well as for update * and insert *): https://docs.delta.io/latest/delta-update.html#-merge-schema-evolution Would be great to have something similar in Hudi. Currently, Hudi tries to use target table schema during MERGE INTO (and drops incoming columns if schema is wider for example). -- This is an automated message from the Apache Git Service.
