> If we somehow set up the HoodieOperation of the record correctly (really check the existence of records), we slow down performance significantly (especially for BUCKET index). If not - we have MERGE INTO working with MOR tables incorrectly. You are right, Hudi upsert/insert into table with primary keys already have the ability to update records, there is no need to use the `MERGE INTO`, `MERGE INTO` is mainly designed for batch ingestion instead of streaming, and for Spark `BLOOM` index, only update/deletes can be written into logs, so I guess we just need to fix it though(it it is not a delete, then it should be an update) -- This is an automated message from the Apache Git Service.
