Package	Description
org.apache.drill.exec.physical.impl.scan.v3	Provides the "version 3" scan framework (which can also be thought of as EVF version 2).
org.apache.drill.exec.physical.impl.scan.v3.file
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.
org.apache.drill.exec.physical.impl.scan.v3.schema	Provides run-time semantic analysis of the projection list for the scan operator.

Classes in org.apache.drill.exec.physical.impl.scan.v3.schema used by org.apache.drill.exec.physical.impl.scan.v3.schema

Class and Description
AbstractSchemaTracker Base class for the projection-based and defined-schema-based scan schema trackers.
DynamicSchemaFilter Projection filter based on the scan schema which typically starts as fully dynamic, then becomes more concrete as the scan progresses.
DynamicSchemaFilter.NewColumnsMode Describes how to handle candidate columns not currently in the scan schema, which turns out to be a surprisingly complex question.
MutableTupleSchema A mutable form of a tuple schema.
MutableTupleSchema.ColumnHandle Holder for a column to allow inserting and replacing columns within the top-level project list.
ProjectedColumn Enhanced form of a dynamic column which records all information from the project list.
ScanProjectionParser.ProjectionParseResult
ScanSchemaConfigBuilder Builds the configuration given to the ScanSchemaTracker.
ScanSchemaResolver.SchemaType Indicates the source of the schema to be analyzed.
ScanSchemaTracker Computes scan output schema from a variety of sources.
