[GitHub] [spark] viirya commented on pull request #34642: [SPARK-37369][SQL] Avoid redundant ColumnarToRow transistion on InMemoryTableScan

   @attilapiros @HeartSaVioR @cloud-fan Added `supportsRowBased`. Now the columnar rule only adds `ColumnarToRowExec` to nodes which only outputs columnar format. If row-based is supported like `InMemoryTableScanExec`, no redundant transition will be added.
