Multithreaded Database Inserts: From Speed to Atomicity. Spring + PostgreSQL

I will tell you how you can speed up data insertion by parallelizing this process in Spring and how to keep the whole operation atomic. We will touch upon batch update in Spring and PostgreSQL, discuss why update is a heavy operation and how we can speed it up in the current technology stack. In addition, I'll look at other approaches to preserving atomicity and show the differences between them in benchmarks.
