BatchScanExec Physical Operator¶

BatchScanExec is a leaf physical operator.

Creating Instance¶

BatchScanExec takes the following to be created:

• Output schema (Seq[AttributeReference])
• Scan

BatchScanExec is created when DataSourceV2Strategy execution planning strategy is executed (for physical operators with DataSourceV2ScanRelation relations).

batch¶

batch: Batch

batch requests the Scan to toBatch.

batch is used when requested for partitions and readerFactory.

inputRDD¶

inputRDD: RDD[InternalRow]

inputRDD creates a DataSourceRDD.

inputRDD is part of the DataSourceV2ScanExecBase abstraction.

partitions¶

partitions: Seq[InputPartition]

partitions...FIXME

partitions is part of the DataSourceV2ScanExecBase abstraction.

readerFactory¶

readerFactory: Seq[InputPartition]

readerFactory...FIXME

readerFactory is part of the DataSourceV2ScanExecBase abstraction.
