Original Abstract Submitted

a system and method of execution node provisioning of a data store with fairness during oversubscription. the method includes scanning, during a first iteration, a queue to identify a first batch of processing requests associated with a plurality of accounts. the method includes determining a total count of demanded execution nodes to satisfy the first batch of processing requests. the method includes determining, based on the total count of demanded execution nodes, an inability for a pool of available execution nodes of a data store to satisfy the first batch of processing requests. the method includes allocating, by a processing device, the first batch of processing requests to the pool of available execution nodes according to a rationing procedure to reduce a latency time associated with processing the first batch of processing requests.
