The federation repo turns (part of) the query plan back into SQL. In the simple case, the query only uses table providers of one remote DBMS. In that case the entire query will be forwarded. In more complex cases, the federation repo splits the plan in pieces that can be sent to each corresponding remote DB. DataFusion pieces together the results to resolve the final query. -- This is an automated message from the Apache Git Service.
