SparklineData Modules

With the 0.4.0 release we support pluggable modules. A plugin can provide extra:

• SQL functions
• Logical Optimizer rules.
• Physical Optimizer rules.
• Rules that transform the parsed Logical Plan before they are processed by the Logical Optimizer.

See the SparklineData Module trait for details on the extension points.

Mysql Compatibility Sample module is an example module.

The spark.sparklinedata.modules controls what modules are loaded. By default this is empty. The setting must be provided when the thriftserver starts; the settings is loaded once and applied to all sessions created in the server.
