## Proposed changes In the past, two conditions needed to be met when sampling a partitioned table: 1. Data is evenly distributed between partitions; 2. Data is evenly distributed between buckets. Finally, the number of sampled rows in each partition and each bucket is the same. Now, sampling will be proportional to the number of partitioned and bucketed rows. ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
