Abstract
Managing a circular transaction log in a data storage system includes receiving requests specifying data to be written to a data object served by the data storage system, and adding log entries to the log containing data specified by the requests at or after a tail of the log and before a head of the log. In response to a trigger event, a size of the log is dynamically increased by inserting additional storage space into the log at or after the tail and before the head, to account for differences between the rate at which entries are added to the log and the rate at which entries are flushed from the log. The disclosed technique may further operate to find the slot position in which each log entry is stored, based on the identifier of the log entry, after inserting the additional storage space into the log.
