Hello Calcite Devs! My name is Charles Givre and I'm the PMC Chair for Apache Drill, which uses Calcite for query planning among other things. I'm working on extending the number of systems that Drill can connect to and I saw that Calcite has a number of adapters for various systems like Cassandra and Elasticsearch.
Could anyone point me to some resources as to how these adapters can be used (or extended) so that Drill could use them? Thank you very much! -- C
