DATA ENGINE INTEGRATION AND DATA REFINEMENT

Data engine integration and data refinement are described. The actions include receiving, by a data refinement engine, a request for data. The actions include determining a first amount of processing to be performed by the data refinement engine and a second amount of processing to be performed by one or more processors of a data source that include a plurality of data nodes. The actions include transmitting, by the data refinement engine, code to the plurality of data nodes of instructions associated with the second amount of processing. The actions include receiving, by the data refinement engine and from the plurality of data nodes, unprocessed first data and processed second data. The actions include processing, by the data refinement engine, the unprocessed first data. The actions include, in response to the request for data, transmitting, by the data refinement engine, the processed first data and the processed second data.
