Modifying a query for processing by multiple data processing systems

A query coordinator comprising:

• a data store;
• and
• one or more processors configured to:
• receive a first query identifying a set of data to be processed and a manner of processing the set of data;
• identify a first portion of the first query is to be executed by a first data processing system and a second portion of the first query is to be executed by a second data processing system;
• generate a modified query based on identifying the first portion of the first query is to be executed by the first data processing system and the second portion of the first query is to be executed by the second data processing system, wherein to generate the modified query, the one or more processors are configured to replace the first portion of the first query with a query identifier;
• define a query processing scheme for obtaining and processing at least a portion of the set of data based on the modified query;
• and
• provide the query processing scheme to the second data processing system,
• wherein a data processing system interface is configured to receive an output of the second data processing system based on the second data processing system processing the query processing scheme, generate a second query to be processed by a component of the first data processing system based on the first portion of the first query and the output of the second data processing system, and provide the second query to the component of the first data processing system.

Non-transitory computer-readable media including computer-executable instructions that, when executed by a query coordinator, cause the query coordinator to:

• receive a first query identifying a set of data to be processed and a manner of processing the set of data;
• identify a first portion of the first query is to be executed by a first data processing system and a second portion of the first query is to be executed by a second data processing system;
• generate a modified query based on identifying the first portion of the first query is to be executed by the first data processing system and the second portion of the first query is to be executed by the second data processing system, wherein to generate the modified query, execution of the computer-executable instructions by the query coordinator, further causes the query coordinator to replace the first portion of the first query with a query identifier;
• define a query processing scheme for obtaining and processing at least a portion of the set of data based on the modified query;
• and
• provide the query processing scheme to the second data processing system,
• wherein a data processing system interface is configured to receive an output of the second data processing system based on the second data processing system processing the query processing scheme, generate a second query to be processed by a component of the first data processing system based on the first portion of the first query and the output of the second data processing system, and provide the second query to the component of the first data processing system.
