> I think this is because Spark 2.4 uses pyrolite 4.13 where it looks the value comparison feature is missing? https://github.com/irmen/Pyrolite/blob/pyrolite-4.13/java/src/main/java/net/razorvine/pickle/Pickler.java#L63-L70 while in Spark 3.x we use pyrolite 4.30 that introduced? and enabled value comparison by default: https://github.com/irmen/Pyrolite/blob/pyrolite-4.30/java/src/main/java/net/razorvine/pickle/Pickler.java#L96-L122 Oh, I see. Thanks for the answer. > I think another option would be to disable the valueCompare explicitly. Yea, I think so, too. Could you try `valueCompare=false` then check performance changes just in case? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
