No user serviceable parts inside. The journal contains information that describes sets of updates done by transactions. In case of a crash, the journal can be replayed to re-apply any updates that may not yet have been written to the on-disk forests.
A transaction does not complete until the journal entry is written to disk, but the corresponding updates to the forest(s) are written later. The database view your queries see are the sum of the on-disk in in-memory stands that comprise forests which make up a database. Journal entries are in a compact binary format that is only used internally by the server to assure data consistency.
