Why I Migrated Away from MongoDB

>Lesson learned - Be very circumspect when turning your back on 40 years of computer science.

So true. We moved away from Mongo for very similar reasons, but we moved to Cassandra instead of Postgres only with great trepidation (we were worried about scalability issues).

Only time will tell if this was a good move or if we should have just done as you did. Good luck out there!
