55. name: mongodb summary: An object/document-oriented database (metapackage) 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. This is a metapackage that depends on all the mongodb parts. provides: database: interface: mongodb peers: replica-set: interface: mongodb-replica-set

The fact that Ubuntu is preferred as a development environment leads to it being the favoured deployment environment (no migration cost) Ubuntu strategy of freely available yet supported has propelled it into this position.
* Wikipedia's architecture has a lot of relationships * Adding 100 of each type isn't hard anymore – thank you config management. * Getting them to work together is still a challenge.
