I found myself completely nodding along to the first half of your comment only to find myself scratching my head to the last half. I'm unfamiliar with Tarantool, but comparing a "server" database like redis with embedded ones like lmdb or rocksdb is so strange. It's comparing different engines to other whole cars. NB: For anyone not in the know, "server" vs embedded here is about how your processes communicate with the DB, not about the type of hardware they're suitable to run on. An embedded database tends to be more of a library that attaches to a file or directory, often from a single process or occasionally from multiple processes on a single host. "Server" databases tend to be connected to from processes on a number of servers over the network. I keep using "server" in quotes here because I don't think I've seen that word used to make the distinction vs embedded databases reliable in literature.
