Spark creates a "canonicalized" plan to determine whether two plan trees produce the same result. If two trees produce the same result, then Spark will reuse shuffle data to reduce the number of stages. In DSv2, the equality of Spark's `BatchScanExec` depends on the equality of the `Scan` produced by sources. This implements `equals` and `hashCode` in `SparkBatchScan` so that the canonicalized plan is equal when scans are equivalent. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
