Notes about Databases
Please keep in mind that each database contains its own system collections, which need to be set up when a database is created. This will make the creation of a database take a while.
Replication is either configured on a per-database level or on server level. In a per-database setup, any replication logging or applying for a new database must be configured explicitly after a new database has been created, whereas all databases are automatically replicated in case of the server-level setup using the global replication applier.
Foxx applications are also available only in the context of the database they have been installed in. A new database will only provide access to the system applications shipped with ArangoDB (that is the web interface at the moment) and no other Foxx applications until they are explicitly installed for the particular database.
