Package	Description
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.
org.apache.drill.exec.physical.impl.scan.v3.schema	Provides run-time semantic analysis of the projection list for the scan operator.
org.apache.drill.exec.physical.resultSet.impl	Handles the details of the result set loader implementation.

Class and Description
BuildFromSchema Build the set of writers from a defined schema.

ColumnState.State Columns move through various lifecycle states as identified by this enum.
ContainerState Abstract representation of a container of vectors: a row, a map, a repeated map, a list or a union.
NullVectorState Do-nothing vector state for a map column which has no actual vector associated with it.
