Here are some learning suggestions referenced from Roman ~ IMO the first thing you need to do is to read the whitepaper [1] to understand the big picture.
Then you can read the Calcite presentation [2] where all main API's are very well described. And the last step, which is my main source of knowledge about Calcite, is to explore the source code of systems that already use Calcite for query processing. I would recommend Apache Ignite [3], Apache Drill [4], Hazelcast [5] and many others that you can find here [6].
