Abstract: Service interruptions in a multi-tenancy, network-based storage system can be mitigated by constraining the execution of queries. In various examples, a network-based storage system may receive a request to execute a query against data maintained by the network-based storage system. The network-based storage system may perform a unit of work to execute the query, progressing through some, but not all, of a set of operations that are to be completed for completing execution of the query. Upon completion of the unit of work, query execution may be paused, query state data may be saved, and query results may be generated for consumption by the requesting computing device. In some embodiments, tokens that are usable to resume query execution based on the saved query state data may be sent to customer computing devices for resuming query execution on-demand.
