A query coordinator can receive and parse a query. Based on parsing the query, the query coordinator can identify one or more components of a first data processing system to obtain and process data according to the query. The query coordinator can define a query processing scheme based on identifying the one or more components and provide the query processing scheme to a second data processing system. Based on providing the query processing scheme, the query coordinator can obtain an output of the second data processing system. The query coordinator can identify a second query based on the output and provide the second query to the one or more components.
