…t number Add a new FE config `max_bucket_num_per_partition` to limit the maximum number of buckets when creating a table or adding a partition. Default value is 768. Changes: 1. Add `max_bucket_num_per_partition` config in Config.java, defaulting to 768 2. Add bucket number validation in `DistributionDescriptor.validate()` for CREATE TABLE scenario 3. Add bucket number validation in `InternalCatalog.addPartition()` for ALTER TABLE ADD PARTITION scenario 4. Add unit tests for the new validation logic 5. Add regression test configurations Behavior: - For user-specified buckets (CREATE TABLE / ALTER TABLE ADD PARTITION): if bucket number exceeds this limit, the operation will be rejected with a helpful error message - For auto-bucket feature (Dynamic Partition): bucket number is capped by `autobucket_max_buckets` automatically, no change - Set to 0 or negative value to disable this limit Cherry-picked from PR apache#61576 and apache#62286
