TengHuo commented on PR #6802:
URL: https://github.com/apache/hudi/pull/6802#issuecomment-1455802492
Hi @yihua
We found an issue in our DeltaStreamer pipeline recently. Our Kafka to Hudi DeltaStreamer pipeline is running slower than 0.10 when we upgraded to 0.12. After checking. We noticed that this issue was caused by this slow stage: `Building workload profile`.
<img width="1782" alt="slow_build_workload_profile" src="https://user-images.githubusercontent.com/7539060/223072527-ea56fae5-d2d3-4843-a3f9-8db008c8f7bb.png">
The parallelism of this stage was 10, which is from this line, https://github.com/apache/hudi/blob/master/hudi-client/hudi-client-common/src/main/java/org/apache/hudi/table/action/commit/HoodieWriteHelper.java#L64
So, even if we setup the config `hoodie.upsert.shuffle.parallelism` as 1000, it will be ignored by the parallelism of input records, which is the number of Kafka topic partition.
May I ask if there is anyway we can improve it? Thanks

Thanks @yihua
Yeah, agree, we have reverted in our internal version. I want to know if there is any better idea for implementing auto-tune?
We can help if there is a solid solution.
