Abstract

In one respect, there is provided a distributed database system. The distributed database system can include a plurality of hosts configured to store and/or manage data, a first query processing engine comprising a master node and an executor node, and a second query processing engine. The master node can be implemented on one or more programmable processors and configured to perform operations. The operations can include: generating an execution plan for a query on data that is stored at and/or managed by one or more of the plurality of hosts; determining to push down, to the second query processing engine, at least one data processing operations in the execution plan; and dispatching, to the executor node, at least a portion of the execution plan, the portion of the execution plan including the at least one data processing operation that is pushed down to the second query processing engine.
