------------------------------------
Summary: Compare batch maxKey to reduce comparisons in
SortMergeReader
Key: FLINK-27958
URL: https://issues.apache.org/jira/browse/FLINK-27958
Project: Flink
Issue Type: Improvement
Components: Table Store
Reporter: Jingsong Lee
Fix For: table-store-0.2.0
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.
