PRIORITIZING DISPERSED STORAGE NETWORK MEMORY OPERATIONS DURING A CRITICAL JUNCTURE

摘要

A method for prioritizing dispersed storage network memory (DSN) operations during a critical juncture. The method begins by a device of the DSN, during a data access request, determining when a DSN memory operation related to the data access request is at a critical juncture. A decode threshold number of encoded data slices is required to recover the data segment, a write threshold number of encoded data slices is required for a successful write operation, and the critical juncture includes the DSN memory operation being within one of a first offset of the decode threshold number and a second offset of the write threshold number. When the DSN memory operation is at the critical juncture, the method continues with detecting an outstanding action with respect to the DSN memory operation, suspending execution of non-critical DSN operations and prioritizing execution of the outstanding action.
