Package org.apache.drill.exec.physical.impl.scan.v3 Description

Provides the "version 3" scan framework (which can also be thought of as EVF version 2). This version provides basically the same API as version 2, but with an implementation driven by schema rather than vectors.

Build a scan using the ScanLifecycleBuilder. Provide a subclass of ReaderFactory that will create each of your ManagedReader instances as needed. The framework handles the details of schemas, missing columns, implicit columns and the rest.
