Abstract
In one embodiment, a computer-implemented method of a distributed database system included the step of providing a query processor to receive a query request and to chart out a query execution plan based on the query request. The method includes the step of providing a data generator to generate a digest list based on the query request, wherein the list of digests comprises each stream or filter applied in servicing the query request. The method includes the step of providing a query engine to obtain a digest list from a multiple-data source as a result of the query request and to filter the digest list. The method includes the step of providing a query worker to obtain the query request and process the query request based on a type of the query request. The method includes the step of providing one or more query worker threads to perform an asynchronous I/O operation for the query request.
