Package
Description
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.
Provides the "version 3" scan framework (which can also be thought of
as EVF version 2).
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.
Provides a second-generation row set (AKA "record batch") writer used
by client code to
Define the schema of a result set.
Write data into the vectors backing a row set.
Handles the details of the result set loader implementation.
Version 3 of the text reader.
