littleeleventhwolf opened a new issue, #8028: URL: https://github.com/apache/hudi/issues/8028
Hudi now provides `preCombine(...)` and `combineAndGetUpdateValue(...)`, which can be used to ensure that a certain write buffer is in order and the snapshot query in order respectively. But in streaming ETL, data disorder is a very common problem, which eventually leads to incorrect query results for users. Is it possible to sort by a certain field in Hudi compaction? That is, the final ETL result and the queried upstream are eventual consistency. What still needs to be considered is how to ensure the correctness of Hudi CDC aggregation result in streaming process when data is out of order. -- This is an automated message from the Apache Git Service.
