Hi Danny0405, I think the support for 2 hudi tables' Spark sort-merge-join with bucket optimization is an important feature. Currently if we join 2 hudi tables, the bucket index's bucket information is not usable by spark, so shuffle is always needs. As explained in [8657](https://github.com/apache/hudi/pull/8657) - hashing- file naming- file numbering- file sorting are different. Unfortunately, according to https://issues.apache.org/jira/browse/SPARK-19256, spark bucket is not compatible with hive bucket yet. So if we have to choose one between spark and hive, I think spark might be of higher priority. -- This is an automated message from the Apache Git Service.
