A server system having one or more processors and memory receives a first query from a requestor and obtains a first query-processing plan including a first plurality of query-processing steps for processing the query. Supported query-processing steps comprise query-processing steps in a set of supported query-processing steps, and unsupported query-processing steps comprise query-processing steps not in the set of supported query-processing steps. In accordance with a determination that the first plurality of query-processing steps includes one or more of the supported query-processing steps and one or more unsupported query-processing steps including a respective unsupported query-processing step, the server system performs the one or more supported query-processing steps to produce intermediate results and generates a first response to the first query that includes the intermediate results and a representation of the respective unsupported query-processing step. The server system transmits the first response to the requestor.
