RonDB (NDB Cluster) takes a different approach to threading and claims it's faster than scylladb-style sharding http://mikaelronstrom.blogspot.com/2021/03/desig

  "ScyllaDB also handles complex query processing in the same engine. RonDB does all complex query processing in MySQL in a separate program." — i.e., as soon as things might get a bit hairy, RonDB punts it off-system. While a clever way to keep performance numbers high, you'd have to also then analyze the MySQL latencies and throughputs to get an overall view of complete system performance. It's a clever dodge, but it's not a magical way to eliminate the need for those pesky CPU cycle times.

    Look a little closer Peter, I doubt you arrived that fast at that conclusion being right. It's not a dodge, the MySQL process is in the same server and can even use shared memory. He claims in total to be better.
