## database.backend, database.host, database.port, database.name & database.replicaset
The database backend to use (e.g. RethinkDB) and its hostname, port and name.
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.
**Example using environment variables**
```text
export BIGCHAINDB_DATABASE_BACKEND=rethinkdb
export BIGCHAINDB_DATABASE_BACKEND=mongodb
export BIGCHAINDB_DATABASE_HOST=localhost
export BIGCHAINDB_DATABASE_PORT=28015
export BIGCHAINDB_DATABASE_PORT=27017
export BIGCHAINDB_DATABASE_NAME=bigchain
export BIGCHAINDB_DATABASE_REPLICASET=bigchain-rs
```
**Example config file snippet**
**Default values**
If (no environment variables were set and there's no local config file), or you used `bigchaindb -y configure rethinkdb` to create a default local config file for a RethinkDB backend, then the defaults will be:
```js
"database": {
"backend": "rethinkdb",
"host": "localhost",
"port": 28015,
"name": "bigchain",
"port": 28015
}
```
If you used `bigchaindb -y configure mongodb` to create a default local config file for a MongoDB backend, then the defaults will be:
```js
"database": {
"backend": "mongodb",
"host": "localhost",
"name": "bigchain",
"port": 27017,
"replicaset": "bigchain-rs"
}
```
**Default values (a snippet from `bigchaindb/__init__.py`)**
```python
'database': {
'backend': os.environ.get('BIGCHAINDB_DATABASE_BACKEND', 'rethinkdb'),
'host': os.environ.get('BIGCHAINDB_DATABASE_HOST', 'localhost'),
'port': int(os.environ.get('BIGCHAINDB_DATABASE_PORT', 28015)),
'name': os.environ.get('BIGCHAINDB_DATABASE_NAME', 'bigchain'),
'replicaset': os.environ.get('BIGCHAINDB_DATABASE_REPLICASET', 'bigchain-rs')
}
```
**Note**: We are currently adding support for MongoDB. The `replicaset` and
`BIGCHAINDB_DATABASE_REPLICASET` option is only used if the `backend` or
`BIGCHAINDB_DATABASE_BACKEND` is set to `"mongodb"`.
