Research direction
Start with ClickHouseAdaptiveQueryExecSuite.scala at line 85 and review the failure reported in the linked CI console log for SPARK-35650. Reproduce the test and determine why the expected partition count differs; done means the test reliably produces the intended count without flaking.
