Abstract: A log unit provides a shared log for recording updates on data objects. Garbage collection is performed locally and in-place by the log unit. In a marking portion of the garbage collection process, the log unit identifies and marks log entries that record mergeable updates. In a deallocation portion of the process, the log unit merges one or more mergeable log entries and deallocates at least portions of the merged log entries.
