Database
From Cluster Documentation Project
- Hadoop is a free Java software framework that supports data intensive distributed applications. It enables applications to work with thousands of nodes and petabytes of data. Hadoop was inspired by Google's MapReduce and Google File System (GFS).
- MongoDB is a high-performance, open source, schema-free document-oriented database. MongoDB is written in C++. A key goal of MongoDB is to bridge the gap between key/value stores (which are fast and highly scalable) and traditional RDBMS systems (which are deep in functionality).
