Alternative to HBase + Map-Reduce

mongoDB

Combining the best features of document databases, key-value stores, and RDBMSes.

MongoDB (from "humongous") is a scalable, high-performance, open source, schema-free, document-oriented database. Written in C++, MongoDB features:

• Document-oriented storage (the simplicity and power of JSON-like data schemas)
• Dynamic queries
• Full index support, including secondary indexes, inner-objects, embedded arrays, geospatial
• Query profiling
• Fast, in-place updates
• Efficient storage of binary data large objects (e.g. photos and videos)
• Replication and fail-over support
• Auto-sharding for cloud-level scalability
• MapReduce for complex aggregation
• Commercial Support, Training, and Consulting

MongoDB bridges the gap between key-value stores (which are fast and highly scalable) and traditional RDBMS systems. Many companies are using MongoDB in production today.
