dalongliu updated FLINK-26929:
------------------------------
Description: We propose an optimization method adaptive hash join for the
batch join scenario, hoping to integrate the advantages of sorted-merge join
and hash join according to the characteristics of runtime data. The adaptive
hash join will try to use hash join strategy firstly, if it failed, will fall
back to sort merge join. (was: We propose an optimization method adaptive hash
