NoSQL LinkedIn Skills Index – December 2014

December 18th, 2014 — Data management

As usual there’s an early finish to the quarter for our NoSQL LinkedIn Skills Index, which tracks mentions of NoSQL database in LinkedIn member profiles, but as usual that has little impact on the results as MongoDB continues to account for 49% of all LinkedIn member profiles mentioning a NoSQL project.

There are a few changes further down the list of NoSQL projects with both Aerospike and OrientDB overtaking Voldemort, as predicted, and RethinkDB overtaking Hypertable.

As noted last quarter, there was a chance that Aerospike might get overtaken by OrientDB and MarkLogic might get overtaken by DynamoDB. As it happens both held off their respective challengers but their places remain under threat.

ArangoDB had the fastest rate of growth in the quarter (21.57%), followed by RethinkDB (21.28%), FoundationDB (19.74%), OrientDB (18.02%) and Aerospike (17.62%). DynamoDB was next, and the fastest growing inside the top ten, with 14.37%.

Of course, we would also note that this is not meant to be a comprehensive analysis, but rather a snapshot of one particular data source.

NoSQL LinkedIn Skills Index – September 2014

October 1st, 2014 — Data management

Time for a new look for our NoSQL LinkedIn Skills Index, which tracks mentions of NoSQL database in LinkedIn member profiles, as it enters its third year. We’ve switched from a bar chart to a line chart to reduce clutter – at least on the horizontal plane.

Unfortunately the dominance of MongoDB means that the chart is inevitably cluttered on the low end of the vertical plane, but the line chart at least provides a clear illustration of that dominance.

There are a few other changes of note further down the list, with FoundationDB gaining a place on Sparksee (as predicted) thanks to it having the fastest rate of growth (40.74%) in Q3. ArangoDB also gained a place on InfiniteGraph thanks to recording the second fastest growth rate (37.84%).

We noted last time that Q3 could see OrientDB overtake Aerospike, unless the release of Aerospike as open source had an immediate impact on interest levels. That seems to have occurred, with Aerospike recording 23.80% growth to not only hold off OrientDB but gain ground on Voldemort, which looks likely to be overtaken by both Aerospike and OrientDB in Q4. Inside the top 10 there is also a chance that DynamoDB could overtake MarkLogic in Q4.

Titan (25.97%), RethinkDB (22.88%) and DynamoDB (22.85%) also deserve a mention in terms of growth in Q3, while Neo4j was the fastest growing of the top 10 with 17.99%. MongoDB was of course most popular NoSQL database by a considerable margin, once again accounting for 49% of all LinkedIn member profiles mentioning a NoSQL project.

NoSQL LinkedIn Skills Index – March 2013

March 26th, 2013 — Data management

As Q1 comes to a close its time to take another look at our NoSQL LinkedIn Skills Index, based on the number of LinkedIn member profiles mentioning each of the NoSQL projects. This is the second update since we rebooted the analysis in September 2012 to account for more products and refine our search terms.

A few interesting statistics to pick out: Neo4j has, as predicted, jumped ahead of MarkLogic for sixth place. No other changes of position, but outside the top ten, shown here, Apache Accumulo continues to grow well.

In fact, Apache Accumulo had the fastest rate of growth for the second quarter in succession, just ahead of DynamoDB and OrientDB -once again – followed by Apache Cassandra and MongoDB.

MongoDB’s growth means that it once again extended its lead as the most popular NoSQL database, according to LinkedIn profile mentions. As the chart below illustrates, it now accounts for 46% of all mentions of NoSQL technologies in LinkedIn profiles, according to our sample, compared with 45% in December.
