             Summary: Batch get statistics of multiple partitions instead of get one by one
                 Key: FLINK-25605
                 URL: https://issues.apache.org/jira/browse/FLINK-25605
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / Planner
            Reporter: Jing Zhang

Currently, `PushPartitionIntoTableSourceScanRule` would fetch statistics of matched partitions one by one.

If there are multiple matched partitions, it costs much time to waiting for get all statistics.
We could make an improvement here to batch get statistics of multiple partitions.
