The Apache Calcite team is pleased to announce the release of Apache
Calcite Avatica 1.28.0.
Avatica is a framework for building database drivers. Avatica defines a
wire API and serialization mechanism for clients to communicate with a
server as a proxy to a database. The reference Avatica client and server
are implemented in Java and communicate over HTTP. Avatica is a
sub-project of Apache Calcite.
Avatica 1.28.0 contains dependency upgrades, support for JDK 24, BEARER
authentication support and bug fixes.
This release is dedicated to Istvan Toth, a prolific contributor to
Avatica who passed away in early 2026. Istvan’s contributions to Avatica
were significant and wide-ranging, including bug fixes, new features,
and improvements to the build system. He was an active member of the
community and his work has had a lasting impact on the project. He will
be greatly missed by all who knew him.
