Apache Arrow ADBC 16 (Libraries) Release

Published 21 Jan 2025
By The Apache Arrow PMC (pmc)

The Apache Arrow team is pleased to announce the version 16 release of the Apache Arrow ADBC libraries. This release includes 15 resolved issues from 11 distinct contributors.

This is a release of the libraries, which are at version 16. The API specification is versioned separately and is at version 1.1.0.

The subcomponents are versioned independently:

  • C/C++/GLib/Go/Python/Ruby: 1.4.0
  • C#: 0.16.0
  • Java: 0.16.0
  • R: 0.16.0
  • Rust: 0.16.0

The release notes below are not exhaustive and only expose selected highlights of the release. Many other bugfixes and improvements have been made: we refer you to the complete changelog.

Release Highlights

This release focused mostly on bugfixes.

The C# ADO.NET adapter can now parse connection properties from the connection string (#2352). The driver for various Thrift-based systems (Hive/Impala/Spark) now supports timeout options (#2312). A package was added to wrap the Arrow Flight SQL driver (written in Go) from C# (#2214).

The PostgreSQL driver was fixed to properly return unknown types as arrow.opaque again (#2450) and to avoid issuing an unnecessary COMMIT which would cause the driver and connection state to get out of sync (#2412).

Python packages only require manylinux2014 again; the baseline glibc requirement was unintentionally raised in the last release and has now been reverted (#2350).

A breaking change was made in the unstable Rust APIs to return a Result from a fallible function (#2334). An adbc_snowflake crate was added to wrap the Snowflake driver (written in Go) into the Rust APIs, though it is not yet being published (#2207).

Roadmap

There is some discussion on a potential second revision of ADBC to include more missing functionality and asynchronous API support. For more, see the milestone; the proposed C Data Interface extensions have been accepted.

We would welcome comments on APIs that could be added or extended, for instance see #1704.

Getting Involved

We welcome questions and contributions from all interested. Issues can be filed on GitHub, and questions can be directed to GitHub or the Arrow mailing lists.
