org.apache.drill.exec.physical.impl.scan.ScanOperatorEvents
Packages that use ScanOperatorEvents
Package
Description
Defines the scan operation implementation.
Handles the special "columns" column used by the text reader,
and available to similar readers.
Handles optional file metadata columns: implicit columns and
partition columns.
Defines the projection, vector continuity and other operations for
a set of one or more readers.
Provides run-time semantic analysis of the projection list for the
scan operator.
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.
