NoSQL Job Trends

Posted by | June 15, 2011 | blog

The NoSQL databases have been red hot as more and more companies are adopting various NoSQL databases for variety of use cases. So the demand for skilled developers with appropriate skills is also increasing. In this post, we will look at NoSQL job trends by analysing job trends for Hadoop, MongoDB, CouchDB, Redis, Riak, Cassandra, Neo4j, Hypertable, SimpleDB, RavenDB.

Here is a graph from

Simplyhired NoSQL Job Trends

This graph displays the percentage of jobs with various NoSQL databases anywhere in the job listing. Since October 2009 till April 2011, the following has occurred:

  • Hadoop jobs increased 113%
  • MongoDB jobs increased 23,598%
  • CouchDB jobs increased 196%
  • Redis jobs increased 7,470%
  • Riak jobs increased 11,565%
  • Cassandra jobs did not change or there is no data available
  • Neo4j jobs decreased 94%
  • Hypertable jobs increased 606%
  • SimpleDB jobs decreased 7%
  • RavenDB jobs increased 88%

The Hadoop is still a leader with very high demand. But the MongoDB has experienced a tremendous growth in demand followed by Riak and Redis. The demand for CouchDB,Hypertable and RavenDB has also increased but at a slower rate compared to their peers in this group. However SimpleDB and Neo4j have shown decline in this period.

The graph from shows data over longer period of time compared to’s graph. This graph also shows that Hadoop is a leader followed by MongoDB, Cassandra and then rest of the group. We can also see that since Jan 10, the demand for CouchDB and Redis has been growing steadily.

What does one conclude from these job trends? Well, it gives you an idea of where do various NoSQL databases stand in terms of jobs in demand. It will also help you decide which specific technology you should pick up if you are looking to land your next hot job in NoSQL land.

    MongoDB growth is actually slightly higher since some job listings will have “mongo” listed instead of “mongodb”

    Neo4j just moved from the Bay Area from Europe, so I expect a big PR/marketing push in addition to further product enhancements.

    Ivan, You are right that some job listings just use mongo instead of mongodb. If we combine search query for mongo and mongodb, that will display MongdDB growth curve slightly higher.

    Re. Neo4j – The move to Bay Area will definitely help Neo4j. They are also hiring for their core engineering team,

    What about stats for the tag ‘NoSQL’?

  • Michael Weir

    On SimplyHired, not sure why you say Cassandra is no change or no data. The data is clearly there and shows only Hadoop with a higher %.

  • Rahul Chaudhary

    Michael, that text is coming from SimplyHired. My guess is that either they are not sure about the data they have for Cassandra or it could simply be a bug in their app.
