In theory, Mentat could run without a long-running persistent log.

Writes are transacted directly against datoms. Consumers that don't ever need to inspect the log — no syncing, no querying the log — could run without the log altogether. Consumers that might need partial log use, e.g., to support observers, could use a transient non-persisted log to handle writes within the lifetime of the process itself.

The upside, of course, is that writes become cheaper and the database becomes smaller.
