NoSQL LinkedIn Skills Index – March 2015

It finally happened: 11 quarters in to our NoSQL LinkedIn Skills Index, which tracks mentions of NoSQL database in LinkedIn member profiles, MongoDB finally hits the 50% mark, representing half of all mentions of NoSQL databases in Q1.

That wasn’t the only change in the rankings in Q1 as there were no fewer than three changes of position in the rankings. In the top 10 DynamoDB overtook MarkLogic to claim ninth place, while lower down OrientDB overtook Aerospike in 12th place, while ArangoDB overtook Sparksee to enter the top 20.

In fact, ArangoDB recorded the highest rate of growth in the quarter, with LinkedIn mentions up 77.4%. We would expect it to overtake FoundationDB in Q2 even if the latter hadn’t just been taken out of the market by Apple. As such we’ll remove it from the rankings next quarter anyway.

It was a good quarter for other multi-model databases as well as ArangoDB as OrientDB climbed a place thanks to 42.5% growth. Aerospike lost that place to OrientDB despite recording the third fastest growth rate, with 29.6%. Other fast climbers were FoundationDB, Titan (despite Aurelius being acquired by DataStax – incidentally Titan will remain in the rankings since it remains available) and RethinkDB.

Inside the top ten, DynamoDB had the fastest growth (20.2%) and stands a chance of gaining another place next quarter by overtaking Riak.

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 – December 2014

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.

Q4donut

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%.

NoSQL LinkedIn Skills Index – September 2014

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 – June 2014

There isn’t a great deal of movement in the June update to our NoSQL LinkedIn Skills Index, which tracks mentions of NoSQL database in NoSQL member profiles. At the tail-end of the list FoundationDB jumped a place above InfiniteGraph and can be expected to gain another place on Sparksee in the next quarter, but otherwise it’s very much ‘as you were’.

Q3 could also see OrientDB overtake Aerospike, unless the recent release of Aerospike as open source his an immediate impact on interest levels. FoundationDB was among those with the fastest growth rates in Q2 at 35.0%, although the faster growth came from ArangoDB (48.0%) followed by RethinkDB (36.6%), Titan (27.1%) and Couchbase (18.9%).

Once again MongoDB was the most popular NoSQL database by a considerable margin, representing 49% of all LinkedIn member profiles mentioning a NoSQL project.

NoSQL LinkedIn Skills Index – March 2014

The latest version of our NoSQL LinkedIn Skills Index shows the continued strength of MongoDB, as the document database increased its share back to 49% of all mentions of NoSQL databases in Q1.

q1_donut

We were surprised to find MongoDB’s proportion of the Index (based on the number of LinkedIn member profiles mentioning each of the NoSQL projects) actually declined in the previous quarter: from 49% to 48%. The Q1 results suggest that was just a blip.

We had wondered whether Couchbase’s leap of two places in our previous update might also be a blip, but in fact Couchbase retained seventh spot in Q1 and there were no changes of position within the top ten this quarter.

q1-chart

Outside the top ten, Titan gained a place on Hypertable, as expected, while RethinkDB leapfrogged AllegroGraph, thanks to recording the third fastest growth (34.94%) in the quarter. The fastest climber, in terms of mentions, was FoundationDB (42.86%), followed by ArangoDB (38.89%). DynamoDB (28.03%) and Titan (26.88%) complete the list of the top five fastest climbers.

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.
