Technologies for asynchronous querying

A database system comprising:

• a network interface to obtain a first message from a user system, wherein the first message includes a user-issued query invoking asynchronous (async) querying;
• a processor system coupled with the network interface, the processor system to:
• generate an async query job (AQJ) entity in response to the invocation of the async querying, the AQJ entity comprising a plurality of fields,
• insert an AQJ identifier (ID) of the AQJ entity into a AQJ queue and into an AQJ ID field of the plurality of fields,
• operate a query engine to convert the user-issued query into a distributed execution instruction set (DEIS), and
• alter a status field of the plurality of fields based on a status of the AQJ entity;
• and
• the network interface is to:
• send a second message to cause the DEIS to be issued to a plurality of data stores, and
• obtain a third message indicating a status of a result set, the result set indicating obtained database objects in a location specified by the user-issued query, and
• store the status of the storing in the status field.

A computer program to be implemented by a cloud computing service, the computer program comprising a set of instructions operable to:

• obtain a distributed execution instruction set (DEIS) from a database system, the DEIS comprising a set of MapReduce (MR) jobs, and the DEIS being based on a user-issued query in a query language that is different from a language of the DEIS;
• identify data stores corresponding to individual MR jobs of the set of MR jobs;
• and
• execute the individual MR jobs to obtain database objects from the corresponding data stores.
