Description
Contributor guide
Research direction
The issue reports unstable SELECT results in the cluster version, but only includes a screenshot without details. Start by examining the cluster execution code and SQL engine components to understand how SELECT queries are processed. Look for concurrency or consistency issues in distributed query execution. Determine what 'unstable' means—varying results or intermittent failures—and write a test to reproduce the behavior.
