The Apache Calcite team is pleased to announce the release of Apache Calcite Avatica 1.9.0.
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. The 1.9.0 release includes various improvements to make it more robust and secure, while maintaining API and protocol compatibility with previous versions. We now include non-shaded and shaded artifacts, to make it easier to embed Avatica in your application. There is improved support for the JDBC API, including better type conversions and support for canceling statements. The transport is upgraded to use protobuf-3.1.0 (previously 3.0 beta).
