Class SelectionBasedTableScan

java.lang.Object
org.apache.calcite.rel.AbstractRelNode
org.apache.calcite.rel.core.TableScan
org.apache.drill.exec.planner.logical.SelectionBasedTableScan
All Implemented Interfaces:
Cloneable, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.hint.Hintable, org.apache.calcite.rel.RelNode
public class SelectionBasedTableScan extends org.apache.calcite.rel.core.TableScan
This class extends from TableScan. It puts the file selection string into its digest. When directory-based partition pruning applied, file selection could be different for the same table.
