If you require SQL, sharding and concurrent writes, yes do use CockroachDB or other equivalent solution. If you don't have those requirements, dqlite or rqlite might get the job done with less moving parts and operational overhead. It's pretty much the same argument of using SQLite vs (say) PostgreSQL, but translated into distributed systems. See: https://www.sqlite.org/whentouse.html https://www.sqlite.org/whentouse.html
