   ### Search before asking
   
   - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.
   
   
   ### Motivation
   
   In SortMergeReader, each sub reader is batched reader.
   
   When adding a new batch to the priority queue, we can look at the maximum key of the batch, and if its maximum key is smaller than the minimum key of other batches, then we can just output the whole batch.

   ### Are you willing to submit a PR?
