Hi Nikita, I agree with your big-picture about differences between such 3 products, just my thoughts about OrientDB cons on "*Immaturity (comparing with others) and Really small company behind the technology (In particular one main contributor), so questions about support, known issues etc.*"
We've many clients in production, some of the clients are enlisted here: http://www.orientechnologies.com/customers/. The gap with Neo4J is not so big in terms of users/clients (considering also that Neo4J is a 10 year old company), and against MongoDB we're much smaller, but all the NoSQL company are much smaller than MongoDB in terms of selling numbers and company size... OrientDB is not (anymore) an one-man project since more than 2 years ago. We've a strong development team and about 40 contributors that help us to improve OrientDB every day: https://github.com/orientechnologies/orientdb/graphs/contributors For the rest, users here (we're about 1,800) worked with both Neo4J and MongoDB and they can give a more objective point of view than mine ;-) Lvc@ On 22 May 2014 12:56, Nikita Sushkov <[email protected]> wrote: > We're starting a new project and looking for an appropriate storage > solution for our case.
