Problem With a large system, it’s easy for one part to affect the performance of other parts. This is true for monoliths but also for more distributed service-oriented systems. Most systems have heavily… Read More »The Bulkhead Pattern: How To Make Your System Fault-tolerant

Locking In On Concurrency Control

Concurrency in a multi-user collaborative environment can be challenging. However, understanding the use case is crucial in picking a solution for handling concurrency. Let’s dive into different solutions for concurrency control in various situations.
