Abstract
A plurality of transactions are executed in a data storage application. As a result, log entries according to the plurality of transactions are stored in at least one log. During a data recovery operation, log entries from the log are dispatched into a plurality of worker queues. Each worker queue corresponds to a different one of a plurality of logical central processing units. The log entries are replayed using the plurality of worker queues such that log entries associated with a same object are executed serially by a single worker queue and at least a portion of the log entries associated with different objects are executed in parallel by different worker queues. Related apparatus, systems, techniques and articles are also described.
