ABSTRACT:
A method for substantially reducing the latency of the database (DB) logging process by removing the agent notification requirement from the DB logger and allowing the DB logger to proceed to the next commit process without the latency of providing each waiting agent a notification that the agent continue their respective processes. When an agent commits a change to persistent storage of the database, the request is received by the logger, which performs the update to the persistent storage. A list of agents waiting on the completion of the commit process is compiled by the logger. The list of agents is provided to and provided to the next committing agent. The next committing agent then notifies the waiting agents that they are able to proceed with their respective processing. The logger may immediately perform the next update to persistent memory without utilizing a substantial amount of time notifying the waiting agents.
