ABSTRACT:
A method and system of journal bundling that provides improved performance. In the preferred embodiment, a journal controller starts a timer to expire at a predetermined maximum time-to-wait. The journal controller then accumulates journal records in a bundle and transmits the bundle to the journal. The journal controller determines the number-of-journal-records accumulated in the bundle based on an adjustable preferred-bundle-size, which it calculates from an average-bundle-size over a history interval. If the timer expires, the journal controller writes the bundle to the journal even if the preferred-bundle-size has not been reached. By basing the preferred-bundle-size on an average-bundle-size over a history interval, the journal controller prevents rapid changes in the journal traffic-rate, which increases journal performance.
