> If you have objects that are happily sharded arbitrarily across machines, don't need joins, transactions, or aggregates calculated on the server, then what are you getting over something like (for example) open-source Redis Cluster? The only reason I can see to prefer MongoDB over Redis Cluster in this case (no joins, no transactions, no aggregations) is if the dataset doesn't fit in memory. Except that, I think you're right to prefer Redis. Your comment is a really interesting comparison of Redis and MongoDB. Never thought about that before. Thanks! |

Don't get me wrong, I'm sure there are use-cases for MongoDB for folks that are not me.
Because background is important; my doctorate is in Algorithms and Data Structures, so Redis basically fits the problem solving algorithms I've been building in my head since before I learned of Redis in 2010. And Postgres (or really any good relational database) is that conceptual next step which took me the better part 2 years of daily SQL (after 8+ years of occasional SQL) to really appreciate.
