             Summary: Evaluate use of Immutables instead of ImmutableBeans
                 Key: CALCITE-4787
                 URL: https://issues.apache.org/jira/browse/CALCITE-4787
             Project: Calcite
          Issue Type: Improvement
            Reporter: Jacques Nadeau


In the creation of CALCITE-3328, [Immutables|https://immutables.github.io/] was discussed as an alternative to a custom implementation. This ticket is to evaluate the impact to the codebase of changing. Ideally, introduction of immutables would both add flexibility and reduce the amount of code associated with these classes.

Immutables works via annotation processor which means that it is should be relatively seamless to build systems and ides.

The switch would also make it easier to work with these objects types in the context of aot compilation tools like GraalVM.
