Abstract
A command log selectively logs commands that have the potential to create conflicts based on instance locks. Lock times can be used to distinguish cases where the instance is locked by the application host at a previous logical time from cases where the instance is concurrently locked by the application host through a different name. A logical command clock is also maintained for commands issued by the application host to a state persistence system, with introspection to determine which issued commands may potentially take a lock. The command processor can resolve conflicts by pausing command execution until the effects of potentially conflicting locking commands become visible and examining the lock time to distinguish among copies of a persisted state storage location.
