…to improve performance #59431 (#66103) ### What problem does this PR solve? Issue Number: close #xxx Related PR: #59431 Problem Summary: Cherry-pick #59431 to branch-4.1. For RANDOM shuffle, the exchange sink used to send blocks to channels in round-robin order one by one. This change collects local channel ids during init and prefers sending to local channels first, reducing network overhead and improving performance. ### Release note None ### Check List (For Author) - Test: No need to test (pure cherry-pick from master with minor conflict resolution on namespace) - Behavior changed: No - Does this need documentation: No
