# Proposed changes change the bucket num compute method in bucket shuffle join ## Problem Summary: When plan bucket shuffle join, we need to know left table bucket number. Currently, we use tablet number directly based on the assumption that left table has only one partition. But, when left table is colocated table, it could have more than one partition. In this case, some data in right table will be dropped incorrectly and produce wrong result for query. reproduce could follow regression test in PR. ## Checklist(Required) 1. Does it affect the original behavior: No 2. Has unit tests been added: No Need 3. Has document been added or modified: No Need 4. Does it need to update dependencies: No 5. Are there any changes that cannot be rolled back: No -- This is an automated message from the Apache Git Service.
