Hi Erik, Coral [1, 2] which is based on Calcite might be a good starting point for this type of work.There are a couple of dialects it supports right now: Hive (or Spark) and Trino (or Presto). You can check out the corresponding test cases [3, 4] for these two dialects. coral-common [5] is a module that contains all Calcite-related infra required to support any dialect. It is extended by both coral-hive and coral-trino.
