refs https://github.com/TryGhost/Ghost/pull/12431 - child_process are more expensive to run comparing to worker_threads (ref. https://wanago.io/2019/05/20/node-js-typescript-14-performance-hooks/) - limiting child process only to sqlite backed instances allows high load servers running with MySQL (most usecases) to continue using worker_threads
