Vitess has an opinionated approach to database scalability. Some of those opinions have minimal controversy such as how durability should be provided via replication, but the one I find interesting is the 250GB per MySQL server recommendation.
Is this a physical MySQL Limit? In short: no. By “physical limit” I mean is there a file format restriction that says databases can not be greater than 250GB?
The physical limit for InnoDB is 64TB per tablespace, and in the default configuration each table is its own tablespace.
