Abstract:
A first plurality of log segments are generated in a data storage application. The log segments are sequentially positioned within a log area and at least one of the log segments contains log hole information identifying a portion of log to skip during replay of the log. Thereafter, a portion of log segments are replayed up to a specified position while skipping at least one portion of the log prior to the specified position that is identified by the at least one log hole. Related apparatus, systems, techniques and articles are also described.
