> As currently approach in `FileSourceScanExec`, the metrics of "numFiles" and "metadataTime"(fileListingTime) were updated while lazy val `selectedPartitions` initialized in the scenario of relation.partitionSchema is set. But `selectedPartitions` will be initialized by `metadata` at first, which is called by `queryExecution.toString` in `SQLExecution.withNewExecutionId`. So while the `SQLMetrics.postDriverMetricUpdates` called, there's no corresponding liveExecutions in SQLAppStatusListener, the metrics update is not work.
