Labels: pull-request-available (was: )
> [Format] C data interface
> -------------------------
>
> Key: ARROW-7912
> URL: https://issues.apache.org/jira/browse/ARROW-7912
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Format
> Affects Versions: 1.0.0
> Reporter: Neal Richardson
> Assignee: Antoine Pitrou
> Priority: Major
> Labels: pull-request-available
>
> Apache Arrow is designed to be a universal in-memory format for the
> representation
> of tabular ("columnar") data. However, some projects may face a difficult
> choice between either depending on a fast-evolving project such as the
> Arrow C++ library, or having to reimplement adapters for data interchange,
> which may require significant, redundant development effort.
> The Arrow C data interface defines a very small, stable set of C definitions
> that can be easily *copied* in any project's source code and used for columnar
> data interchange in the Arrow format. For non-C/C++ languages and runtimes,
> it should be almost as easy to translate the C definitions into the
> corresponding C FFI declarations.
> Applications and libraries can therefore work with Arrow memory without
> necessarily using Arrow libraries or reinventing the wheel. Developers can
> choose between tight integration
> with the Arrow *software project* (benefitting from the growing array of
> facilities exposed by e.g. the C++ or Java implementations of Apache Arrow,
> but with the cost of a dependency) or minimal integration with the Arrow
> *format* only.
