Package
Description
Drill expression materialization and evaluation facilities.
Standard type conversion tools for the case in which the input
types are the standard Java types already supported by the
ValuesWriter
interface.Provides the "version 3" scan framework (which can also be thought of
as EVF version 2).
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.
The "row set model" provides a "dual" of the vector structure used to create,
allocate and work with a collection of vectors.
Implementation of a row set model for hyper-batches.
This set of classes models the structure of a batch consisting
of single vectors (as contrasted with a hyper batch.) Provides tools
or metdata-based construction, allocation, reading and writing of
the vectors.
Provides a set of tools to work with row sets.
Version 3 of the text reader.
Defines a mock data source which generates dummy test data for use
in testing.
Provides a light-weight, simplified set of column readers and writers that
can be plugged into a variety of row-level readers and writers.
Provides the reader hierarchy as explained in the API package.
Implementation of the vector writers.
This package provides a "dummy" set of writers.
JDBC driver for Drill.
