I was recently prompted by OrientDB CEO Luca Garulli to take another look at the NoSQL LinkedIn Skills Index, which we previously updated on a regular basis between September 2012 and 2015.
I wouldn’t read too much into the results since there’s been such a long period between updates, and this is – as ever – just a snapshot of one particular data source. However, they are definitely interesting, especially when you consider that we retired the NoSQL LinkedIn Skills Index primarily because the results had become so boringly predictable.
As such I’d make the following observations without any additional comment:
- It is interesting to note that MongoDB’s share of mentions of NoSQL databases in LinkedIn member profiles has declined since September 2015, from 51% to 48%. Of course, MongoDB remains the number one by a considerable margin.
-
It is also interesting to note that Redis has climbed above Cassandra to claim second spot.
- Similarly it is interesting that Neo4j has climbed above CouchDB for fifth place.
- And it is also interesting that DynamoDB has overtaken Couchbase for eighth place.
- It is also interesting that the two fastest growing NoSQL databases, in terms of mentions in LinkedIn profiles, are Google Cloud Bigtable (up 557%) and Azure DocumentDB (up 254%).
- And it is also interesting that the third fastest growth came from RethinkDB, despite the recent demise of the company of the same name.
- Those growth rates saw Google Clooud Bigtable climb above Voldemort, ArangoDB, Hypertable and Allegrograph, while Azure DocumentDB climbed above Titan and Voldemort, and RethinkDB climbed above Titan and Accumulo.
Since Luca prompted another look at the results, I should also probably point out that mentions of OrientDB grew at a healthy 83% as OrientDB held on to 11th place in the Index.
Interesting…

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.

There’s an early end to the quarter for our NoSQL LinkedIn Skills Index, based on the number of LinkedIn member profiles mentioning each of the NoSQL projects, just as there was in 2012.
We predicted in Q3 that Couchbase would overtake MarkLogic this quarter, which came to pass, but were somewhat surprised to see Couchbase also leapfrog Riak to claim 7th place. It’s almost too close to call between the three, though we wouldn’t be surprised to see those places change hands in the coming quarters.
There were no other changes of position outside the top ten, although Titan is bearing down on Hypertable having recorded the fastest growth in Q4 (49.5%) and can be expected to gain a place in Q1 2014. The second fastest climber, in terms of mentions, was FoundationDB, followed by ArangoDB, RethinkDB and Apache Cassandra (the latter being particularly notable since it was the only one of the five fastest growers to also be one of the top ten most mentioned in LinkedIn member profiles).
That growth was of course not enough to close the gap on MongoDB as the most mentioned NoSQL database in LinkedIn member profiles, although for the first time MongoDB’s proportion of the overall total actually declined – from 49% in Q3 to 48%, upsetting our prediction that MongoDB would pass the 50% threshold in Q4.
It will be interesting to see whether MongoDB’s dominance declines again in Q1, although either way it retains a monumental lead over all the other NoSQL databases in terms of mentions in LinkedIn profiles.
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.
