Packages that use ManagedReader

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.
