Looks good to me. I don't see that SortMergeJoin is required to use this trait. |

Which issue does this PR close?
Closes #.
Rationale for this change
EagerJoinStreamtrait is currently implemented only bySymmetricHashJoin. It was initially designed to be open-ended for other joins that could potentially work with an eager polling strategy. However, this strategy does not provide significant benefits or serve as a better alternative to other strategies. It is specifically suited to the nature ofSymmetricHashJoin. Therefore, the implementation has been moved directly toSymmetricHashJoin.Although it was suggested that
SortMergeJoinmight utilize this strategy, it does not require such a polling mechanism.For simplification, this PR removes the redundant trait implementation and moves the existing implementation to where it is actually needed. If this trait is being utilized downstream, please share your thoughts.
