I’m at the beginning of looking into graph-DBs. I like the look of OrientDB, but I came across this comparison between ArangoDB and OrientDB. What concerned me was this comment:
we faced a long string of problems which were a direct result of how OrientDB is developed, rather than anything being wrong with it conceptually. To put it simply, it is not developed to the high standards that you’d expect from a database vendor, and while it claims a lot of features, a lot of those features are half baked or just don’t work. We spent a lot of time and effort working on OrientDB for our clients, and in the end it disappointed all of them.
The comment was admittedly back in Feb/16. I’m interested in opinions on OrientDB’s reliability now - general operation as well as in multi-master and sharding scenarios.
I also note that ArangoDB has been catching up OrientDB.
