Published 08 Jan 2024
By The Apache Arrow PMC (pmc)

The Apache Arrow team is pleased to announce the 0.9.0 release of the Apache Arrow ADBC libraries. This covers includes 34 resolved issues from 16 distinct contributors.

This is a release of the libraries, which are at version 0.9.0. The API specification is versioned separately and is at version 1.1.0.

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

The C#/.NET implementation is gearing up for a proper release and has had various bugfixes in the core libraries, the drivers, and the ADO.NET wrapper.

The Go implementation now supports executing more methods (like ConnectionCommit) when importing a native C/C++ driver.

The PostgreSQL driver can now write decimal values and dictionary-encoded string/bytestring. Also, AdbcConnectionGetTableSchema was fixed to handle the catalog and schema parameters correctly, and the driver now tries to provide a row count for non-select queries.

The Python bindings now accept a PyArrow Dataset as a data source for bulk ingestion. The new PyCapsule interface is supported. It is possible to build the Python packages via CMake, which simplifies handling the mixed-C++-and-Python builds.

The R bindings reference-count objects to try to detect improper usage and avoid crashes.

The Snowflake driver properly handles escaping and case sensitivity in various metadata methods. It also now supports StatementExecuteSchema.

The Javadoc API reference is now included in the documentation.
