yeah, with global index use-case, especially when there is a clash between two records just wrt partition path, depending on the [config value](https://hudi.apache.org/docs/configurations#bloomindexupdatepartitionpathupdatepartitionpath--false) set, hudi does either of these two. a. delete existing storage record in old partition and insert to new partition or b. update incoming record to same old partition (ignoring the new partition. In this flow hudi does not honor preCombine. PreCombine will be honored when an updates happen. for eg (b) in above scenario. Or just regular updates where both record key and partition path matches -- This is an automated message from the Apache Git Service.
