MongoDB 2.4 Released

Date 2013/3/19 9:19:37 | Topic: Product News

The general availability of MongoDB 2.4 was announced today by 10gen. database. New capabilities include Hash-based Sharding, Capped Arrays, Text Search, Geospatial Enhancements and a number of other key features. In addition, 10gen introduced MongoDB Enterprise as part of a new MongoDB Enterprise subscription level. MongoDB Enterprise contains new monitoring and security features including Kerberos Authentication and Role-based Privileges.


MongoDB 2.4 key features and enhancements include:

* Hash-based Sharding – MongoDB provides horizontal scaling by transparently sharding data across multiple physical servers. MongoDB 2.4 now includes Hash-based Sharding, a new option that simplifies the creation of large-scale MongoDB systems.  
* Capped Arrays – Applications frequently provide real-time visibility into top ranking attributes, such as leaderboards and most viewed, emailed or purchased items. Capped Arrays simplify development by allowing developers to easily maintain a sorted array of fixed length within documents.
* Text Search (Beta) – Search is the primary interface for navigating data in many applications. MongoDB’s native, real-time Text Search simplifies development and deployment for MongoDB users with stemming and tokenization in 15 languages.*
* Geospatial Enhancements – Mobile and social applications and government programs rely on location and sophisticated geospatial analysis. MongoDB 2.4 introduces GeoJSON support, a more accurate spherical model and polygon intersections.*
* Faster Counts – Count operation performance has improved, including low cardinality index-based counts that are 20x faster than prior releases of MongoDB.
* Aggregation Framework Improvements – Performance for real-time analysis of data using MongoDB’s Aggregation Framework is now 3 - 5x faster for most operations.
* Working Set Analyzer – MongoDB is used in applications where real-time, low-latency performance is critical. The Working Set Analyzer helps users maximize their performance and their capacity planning based on analysis of resource utilization.
* Improved Replication – MongoDB 2.4 intelligently determines when to initiate the election of a new primary replica during network hiccups. Replication is now significantly faster for initial synchronization, providing greater flexibility and lower risk for maintaining system availability.

MongoDB Enterprise features include:
* Monitoring – On-prem monitoring, visualization and alerting on more than 100 operational metrics of a MongoDB system in real time, based on the same application that powers 10gen’s popular MongoDB Monitoring Service (MMS).*
* Kerberos Authentication – Enterprise applications can now securely authenticate with MongoDB using this widely adopted standard.

* Role-based Privileges – Separate responsibilities for server, database and cluster administration.

MongoDB is the open-source, document database popular among developers and IT professionals due to its agile and scalable approach. MongoDB provides a JSON data model with dynamic schemas, extensive driver support, auto-sharding, built-in replication and high availability, full and flexible index support, rich queries, aggregation, in-place updates and GridFS for large file storage. s one of the most popular new technologies, MongoDB has more than 4 million downloads, 50,000 Online Education registrations, 15,000 MongoDB User Group (MUG) members, 14,000 MongoDB Monitoring Service users and 10,000 attendees at MongoDB global events in 2012.
