## database.backend, database.host, database.port, database.name & database.replicaset
## database.*
The database backend to use (`rethinkdb` or `mongodb`) and its hostname, port and name. If the database backend is `mongodb`, then there's a fifth setting: the name of the replica set. If the database backend is `rethinkdb`, you *can* set the name of the replica set, but it won't be used for anything.
The settings with names of the form `database.*` are for the database backend
(currently either RethinkDB or MongoDB). They are:
* `database.backend` is either `rethinkdb` or `mongodb`.
* `database.host` is the hostname (FQDN) of the backend database.
* `database.port` is self-explanatory.
* `database.name` is a user-chosen name for the database inside RethinkDB or MongoDB, e.g. `bigchain`.
* `database.replicaset` is only relevant if using MongoDB; it's the name of the MongoDB replica set, e.g. `bigchain-rs`.
* `database.connection_timeout` is the maximum number of milliseconds that BigchainDB will wait before giving up on one attempt to connect to the database backend.
* `database.max_tries` is the maximum number of times that BigchainDB will try to establish a connection with the database backend. If 0, then it will try forever.
