Directory Per DB

When true, MongoDB uses a separate directory to store data for each database. The directories are under the storage.dbPath directory, and each subdirectory name corresponds to the database name.

The storage.directoryPerDB setting is available only for mongod.

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb
  journal:
    enabled: true
  directoryPerDB: true

Max Incoming Connections

The maximum number of simultaneous connections that mongos or mongod will accept. This setting has no effect if it is higher than your operating system's configured maximum connection tracking threshold. Default : 65536

# network interfaces
net:
  port: 27017
  bindIp: 127.0.0.1
  maxIncomingConnections: 65536

Process Management

Fork

Enable a daemon mode that runs the mongos or mongod process in the background. By default mongos or mongod does not run as a daemon: typically you will run mongos or mongod as a daemon, either by using processManagement.fork or by using a controlling process that handles the daemonization process (e.g. as with upstart and systemd). Default : false

# how the process runs
processManagement:
  fork: true
  timeZoneInfo: /usr/share/zoneinfo

Replication

Replica Sets

A replica set is a group of MongoDB servers, called nodes, containing an identical copy of the data. If one of the servers fails, the other two will pick up the load while the crashed one restarts. [1]
