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.

Key-value store system

Disclosed herein is a modular computing device that provides a user options to upgrade an existing computing device as improved expansion units become available without rendering the underlying base unit obsolete. The base unit of the modular computing device receives high-voltage AC power and one or more power supplies within the base unit converts the AC power to low-voltage DC power that is consumed within the base unit. An AC power transfer unit transfers AC power from the base unit to an expansion unit installed within an expansion dock of the base unit. One or more power supplies within the expansion unit convert the received AC power to low-voltage DC power that is consumed within the expansion unit.
