Incredibly cool! It shows running Ubuntu and Postgres, and also supports full posix operations.

Questions:

- I see there is a diagram running multiple Postgres nodes backed by this store, very similar to horizontally distributed web-server. Doesn't Postgres use WAL replication? Or is it disabled and they are they running on same "views" of the filesystem?

- What does this mean for services that handle geo-distribution on app layer? e.g. CockroachDB?

Sorry if this sounds dumb.
