org.apache.drill.exec.physical.impl.scan.ScanOperatorEvents

Packages that use ScanOperatorEvents

Package	Description
org.apache.drill.exec.physical.impl.scan	Defines the scan operation implementation.
org.apache.drill.exec.physical.impl.scan.columns	Handles the special "columns" column used by the text reader, and available to similar readers.
org.apache.drill.exec.physical.impl.scan.file	Handles optional file metadata columns: implicit columns and partition columns.
org.apache.drill.exec.physical.impl.scan.framework	Defines the projection, vector continuity and other operations for a set of one or more readers.
org.apache.drill.exec.physical.impl.scan.project	Provides run-time semantic analysis of the projection list for the scan operator.
org.apache.drill.exec.physical.impl.scan.v3.lifecycle	Implements the details of the scan lifecycle for a set of readers, primarily the process of resolving the scan output schema from a variety of input schemas, then running each reader, each of which will produce some number of batches.
