Class SplunkTableScan

java.lang.Object

org.apache.calcite.rel.AbstractRelNode

org.apache.calcite.rel.core.TableScan

org.apache.calcite.adapter.splunk.SplunkTableScan

All Implemented Interfaces:

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

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

Relational expression representing a scan of Splunk.

Splunk does not have tables, but it's easiest to imagine that a Splunk instance is one large table. This "table" does not have a fixed set of columns (Splunk calls them "fields") but each query specifies the fields that it wants. It also specifies a search expression, and optionally earliest and latest dates.
