Vitess deserves more love here on HN. It's incredible the way it gives you the best of both worlds (RDBMS and NoSQL). Most operations end up in a single shard, so you have no performance impact and still have the benefit of built in MySQL joins and relational integrity. It is built to be container-native, so the recommended usage is to split into 100-300 GB chunks, which simultaneously makes schema changes take 1/(n shards) of the time for a normal ALTER TABLE.
