HSQLDB Avatica server for older Apache Calcite releases

Apache Calcite Avatica 1.8.0 will include a standalone artifact which starts an Avatica server instance using an embedded HSQLDB server. This project aims to provide the same functionality against older versions of Avatica/Calcite.

This is desired to enable cross-version compatibility tests for Avatica's RPC framework.

Building

By default, Calcite 1.6.0 is built against. This can be changed by specifying -Dcalcite.version=<...> on the Maven command line.

To build against Calcite-1.7.x series releases, the post-avatica-split Maven profile must also be activated, e.g. -Dcalcite.version=1.7.1 -Ppost-avatica-split.

Running

The server can be started using the provided shaded jar

java -jar target/legacy-avatica-hsqldb-server-0.0.1-SNAPSHOT-avatica-1.6.0.jar
