MongoDB v2.4 was released in March 19. It introduced the built-in text search function, hash-based sharding, and expected security features.

At the same time, 10gen released the MongoDB Enterprise Edition, which adds the security and monitoring features on the basis of the open-source edition, and is easy to integrate with other enterprise software.

Lack of security makes nosql technology widely criticized. MongoDB Enterprise Edition adds Role-Based Access Control, which means that the user's permissions can be better controlled. You can also select an SSL certificate that requires the client to provide a signature. MongoDB Enterprise Edition also supports Kerberos authentication.

MongoDB text search, as one of its new features, is considered a "Basic" feature. But it does not mean it is a replacement of SOLR and Lucene.

For hash-based sharding, you can ensure that the Read and Write distribution of MongoDB is relatively even under the shards of a large cluster. The "Working Set Size Analyser" analysis tool can evaluate the memory capacity that MongoDB expects to use.

In addition, MongoDB adds two new types of objects that can be stored:
1. capped Arrays
The capped array is declared as a fixed-size 2D geospatial index.
2. Existing 2D Indexes

In addition, the Firefox spidermonkey JavaScript engine, which was originally used for MongoDB's mapreduce functions, $ where and shell environments, has now been replaced by Chrome's V8 engine.

The following is a comparison of functions of the MongoDB open-source edition and the Enterprise Edition:
