I've been working on a Calcite adapter for Apache Geode.
Current implementation uses the plain Geode API and OQL(Object Query Interface) to push down relational expressions such as projections, filtering, sorting, and grouping .
Provided functionality can hopefully address certain Geode use cases and will provide a stepping stone for future improvements.
Here are some remaining tasks as i see it:
- New tests for test suite (and update calcite-test-dataset to support Geode)
- Add Integration tests that use calcite-test-dataset
