kwondw opened a new pull request #1703: URL: https://github.com/apache/hudi/pull/1703
## What is the purpose of the pull request For Delete API, I noticed "hoodie.delete.shuffle.parallelism" isn't used as opposed to "hoodie.upsert.shuffle.parallelism" is used for [upsert](https://github.com/apache/hudi/blob/master/hudi-client/src/main/java/org/apache/hudi/table/action/commit/WriteHelper.java#L104), this creates the performance difference between delete by upsert API with "EmptyHoodieRecordPayload" and delete API for certain cases. https://issues.apache.org/jira/browse/HUDI-993 has more detail. ## Brief change log * Let [deduplicateKeys](https://github.com/apache/hudi/blob/master/hudi-client/src/main/java/org/apache/hudi/table/action/commit/DeleteHelper.java#L51-L57) method use "hoodie.upsert.shuffle.parallelism" * Repartition inputRDD as "hoodie.upsert.shuffle.parallelism" in case "hoodie.combine.before.delete=false" ## Verify this pull request This change added tests and can be verified as follows: ## Committer checklist - [X] Has a corresponding JIRA in PR title & commit - [X] Commit message is descriptive of the change - [ ] CI is green - [X] Necessary doc changes done or have another open PR - [X] For large changes, please consider breaking it into sub-tasks under an umbrella JIRA. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
