Sugamber edited a comment on issue #2637: URL: https://github.com/apache/hudi/issues/2637#issuecomment-804636424 I have created one class after implementing HoodieRecordPayload. We have three methods for which we have to write our logic. 1. preCombine 2. combineAndGetUpdateValue 3. getInsertValue @n3nash As per your above explanation, preCombine would provide the current record which is coming in incremental load and combineAndGetUpdateValue will provide the latest records from hoodie table. Please correct me if my understanding is incorrect. In my use case , I'm only getting few columns out of 20 in incremental data. I have built schema in constructor as preCombine method does not have any schema details. For Example - Hudi table built with 20 columns. Now, requirement is to update only 3 columns and only these columns data is coming from incremental data feeds along with RECORDKEY_FIELD_OPT_KEY,PARTITIONPATH_FIELD_OPT_KEY and PRECOMBINE_FIELD_OPT_KEY column. I have implemented the class as below. Please let me know in which method, I'll be getting full schema of the table. I also found that getInsertValue method is getting invoked even this is not called in combineAndGetUpdate method. I would like to know more about these three methods and its flow. -- This is an automated message from the Apache Git Service.
