Class ProcessGroupStatusTableScan

java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.calcite.rel.core.TableScan

org.apache.nifi.reporting.sql.processgroupstatus.ProcessGroupStatusTableScan

All Implemented Interfaces:

Cloneable, org.apache.calcite.adapter.enumerable.EnumerableRel, org.apache.calcite.plan.RelOptNode, org.apache.calcite.rel.RelNode

public class ProcessGroupStatusTableScan
extends org.apache.calcite.rel.core.TableScan
implements org.apache.calcite.adapter.enumerable.EnumerableRel

Relational expression representing a snapshot (at scan time) of status for all process groups (PGs) in the flow.

Like any table scan, it serves as a leaf node of a query tree.
