The MongoDB NoSQL Database Blog

This is a guest post by Nosh Petigara, president of Analytica

Analytica is an analytics platform that makes it easy to analyze and report on data like user profiles, event logs, product catalogs, user-generated content, financial assets, or anything else you may have stored in you MongoDB database.

Analytica is built from the ground up for rich document type data and uses a JSON-like representation throughout its architecture. You use Analytica Script a declarative expression language tailored for JSON data, to tell Analytica how perform calculations, filter, group, and transform your documents into the results you want. You can interact with Analytica using a plug-in to Microsoft Excel or a command line shell.  Analytica can also be used through its REST API. Browser-based and mobile interfaces are coming soon.

Note: while this blog post uses some Linux commands in its examples, mongoperf runs and is useful on just about all operating systems.

mongoperf is a utility for checking disk i/o performance of a server independent of MongoDB. It performs simple timed random disk i/o’s.

mongoperf has a couple of modes: mmf:false and mmf:true  

mmf:false mode is a completely generic random physical I/O test — there is effectively no MongoDB code involved.

Text search (SERVER-380) is one of the most requested features for MongoDB 10gen is working on an experimental text-search feature, to be released in v2.4, and we’re already seeing some talk in the community about the native implementation within the server. We view this as an important step towards fulfilling a community need. 

MongoDB text search is still in its infancy and we encourage you to try it out on your datasets. Many applications use both MongoDB and Solr/Lucene, but realize that there is still a feature gap. For some applications, the basic text search that we are introducing may be sufficient. As you get to know text search, you can determine when MongoDB has crossed the threshold for what you need.

You can configure text search in the mongo shell:

db.adminCommand( { setParameter : 1, textSearchEnabled : true } )

Or set a command:

mongod --setParameter textSearchEnabled=true
