Module journal

An append-only log for storing arbitrary data.

Journals provide append-only logging for persisting arbitrary data with fast replay, historical pruning, and rudimentary support for fetching individual items. A journal can be used on its own to serve as a backing store for some in-memory data structure, or as a building block for a more complex construction that prescribes some meaning to items in the log.
