The rationale that we don't make every little thing atomic by default is, that there's a effectiveness Value and for most issues Do not actually need thread security. A couple of parts of our code require it and for anyone couple sections, we must compose our Atomic Wallet code in the thread-safe way utilizing locks, mutex or synchronization.

"Ham and eggs" only jumped by one Despite the fact that two men and women voted for it! This is often Obviously not what we wanted. If only there was an atomic Procedure "increment if it exists or make a new report"... for brevity, let's phone it "upsert" (for "update or insert")
