Abstract
Systems, methods, and data storage devices for management of key-value delete operations for namespaces supporting multiple hosts are described. Responsive to a delete command, the key for the deleted key-value pair may be moved to a deleted data structure having a delete order. During garbage collection erase blocks corresponding to the key-value pairs may be invalidated based on the delete order and removed from the deleted data structure.
