Apache Arrow ADBC 0.10.0 (Libraries) Release

Published 22 Feb 2024
By The Apache Arrow PMC (pmc)

The Apache Arrow team is pleased to announce the 0.10.0 release of the Apache Arrow ADBC libraries. This covers includes 31 resolved issues from 18 distinct contributors.

This is a release of the libraries, which are at version 0.10.0. 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 BigQuery driver now handles large result sets, and supports passing a scope when authenticating. It also has better support for ARRAY types.

The C++ implementation now requires C++17 or later.

The Flight SQL driver now supports the incremental execution feature with Flight SQL services that implement PollFlightInfo. Also, it will reuse credentials/cookies when creating sub-clients to fetch data.

The Go libraries now expose a Close method on AdbcDatabase structs; this is a potentially breaking change.

The Java implementation now has Checker Framework nullness annotations. The driver manager interface was overhauled; this is a breaking change to the library APIs. The Java Flight SQL driver now supports getObjects.

The PostgreSQL driver will add the PostgreSQL type name to the field metadata of columns of NUMERIC type. Also, it now handles ENUM types.

The Python bindings now return the underlying PyArrow RecordBatchReader when requested, instead of the “wrapped” reader, due to a crash. This means that callers will not get ADBC-wrapped exceptions from the reader. Also, Ctrl-C will now interrupt ADBC operations on the main thread.

The Snowflake driver now has much, much faster bulk ingestion speed as it now uploads bulk Parquet files instead of using bind parameters.
