Abstract: Updates to an immutable log may be cached. An immutable log may be stored in a non-volatile storage and an end portion of the immutable log may be stored in a volatile storage as a cache. Reads to obtain records from the end portion of the log may be obtained from the cache instead of the non-volatile storage if the requested records are present in the cache.
