LogicalRDD — Logical Scan Over RDD

LogicalRDD is a leaf logical operator with MultiInstanceRelation support for a logical representation of a scan over RDD of internal binary rows.

LogicalRDD is created when:

Note
LogicalRDD is resolved to RDDScanExec when BasicOperators execution planning strategy is executed.

Computing Statistics — computeStats Method

computeStats(): Statistics
Note
computeStats is part of LeafNode Contract to compute statistics for cost-based optimizer.
