Today is the NoSQL installment of the February job trends. For the NoSQL job trends, I am continuing to focus on Cassandra, Redis, Voldemort, SimpleDB, CouchDB, MongoDB, HBase, and Riak. As was stated previously, Hadoop continues to be the clear leader in demand and still flattens the trends of other solutions. However, the gap is steadily shrinking and Hadoop could be included in the near future.

First, let’s look at the trends from Indeed:

Indeed No Sql Job Trends - February 2013

MongoDB continues to lead the pack since the beginning of 2011. Cassandra has had a rocky trend over the past year without any real net growth. HBase has grown nicely in 2013, challenging Cassandra as one of the top tools. Besides the last few months, Redis has been growing very well. It cannot keep pace with the other leaders. CouchDB is losing ground as its growth has stagnated for over a year, although this looks to be due to the split of Couchbase. Riak has had difficulty growing in 2012, while the other tools grow rapidly. SimpleDB cannot seem to grow, even though there have been signs of life over the past few years. Voldemort continues to trail the pack showing no real growth.

Now, it’s time for the short term trends of SimplyHired:

SimplyHired No Sql Job Trends - February 2013

Overall, SimplyHired is showing fairly flat trends for the past six months. These trends look very similar to the Indeed long-term trends. MongoDB leads with Cassandra, HBase and Redis forming the middle pack. Like Indeed, CouchDB shows a flat trend for the year, and Riak also showing no growth during 2012. SimpleDB and Voldemort trail all of the tools, with a bad flat and possibly negative trend.

Finally, we look at the relative growth trend from Indeed:

Indeed No Sql Job Growth - February 2013

HBase continues to show outrageous growth in what is a high growth area. Cassandra’s growth trend has hit a plateau, but it is a very high one. MongoDB may lead the overall demand, but its growth trend is only third. Riak and Redis are showing similar growth, around 2500%. CouchDB barely leads SimpleDB and Voldemort with minimal growth. These growth trends have changed drastically in the past year, as demand starts to get more mainstream.

MongoDB continues to lead the demand, but HBase and Cassandra are showing stronger growth. Redis has solid demand and growth, but the growth is not fast enough to catch the other tools. Riak does not seem to be gaining the adoption of the other tools, as its demand and relative growth are just not special. CouchDB is an interesting case, where it has decent demand, but its growth is being affected by the split with Couchbase. As more things change between the two solutions, the trends should be watched. In our case, Couchbase will be added to these trends in the next edition. For whatever reason, SimpleDB has never seen the growth you would have expected, but it is enough to remain on this list. Voldemort’s demand and growth have not been positive, and it will be replaced by Couchbase in this analysis in the future. Overall, this means the choices for NoSQL tools is actually becoming more complicated. There are now several solid options with Hadoop, MongoDB, Cassandra, HBase and Redis.

As always, if there are other NoSQL tools that should be included, please let me know in the comments.
