A system includes a processor and a memory storing multiple records in a key-value data structure and processor executable instructions for managing access to records in the key-value data structure. The instructions are executable to perform operations including managing a shared atomic epoch counter and thread epoch counters, determining a maximal safe epoch as a function of the shared atomic epoch counter and the thread epoch counters, maintaining a drain list of trigger actions, and triggering the trigger actions in the drain list as a function of an update of the shared atomic epoch counter and the maximal safe epoch.
