Apache Arrow ADBC 0.3.0 (Libraries) Release
21 Mar 2023
By The Apache Arrow PMC (pmc)
This is a release of the libraries, which are at version 0.3.0. The API specification is versioned separately and is at version 1.0.0.
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.
R bindings for the driver manager have been added, as well as an R package that repackages the SQLite driver.
The ADBC Flight SQL driver now supports transactions and executing Substrait plans. Also, it has had several bugs fixed, including setting timeouts and sending headers properly.
The Python ADBC packages now expose enums for driver-specific options. Also, the DBAPI layer now implements
__del__ on objects to assist in cleaning up resources (though context managers are still recommended).
The ADBC JDBC driver now exposes more metadata about constraints via
