- ### BEGIN INIT INFO
- # Provides: mongod_data_d
- # Required-Start: $network $local_fs $remote_fs
- # Required-Stop: $network $local_fs $remote_fs

- # Short-Description: An object/document-oriented database
- # Description: MongoDB is a high-performance, open source, schema-free
- # document-oriented data store that's easy to deploy, manage
- # and use. It's network accessible, written in C++ and offers
- # the following features:
- #
- # * Collection oriented storage - easy storage of object-
- # style data
- # * Full index support, including on inner objects
- # * Query profiling
- # * Replication and fail-over support
- # * Efficient storage of binary data including large
- # objects (e.g. videos)
- # * Auto-sharding for cloud-level scalability (Q209)
- #
- # High performance, scalability, and reasonable depth of
- # functionality are the goals for the project.
