Your read model and write model being the same is a common issue in system design, and CQRS highlights this problem. However, many explanations simplify CQRS as a binary choice: either you implement it or you don't.
In reality, CQRS is more like a ladder. In my latest video, I break down CQRS into four levels, each corresponding to specific challenges that arise as a system scales. Each level addresses a unique problem and comes with its own complexities.
The common pitfall? Teams often leap to the most advanced level, assuming it’s the best approach, and end up with unnecessary complexity. The lower levels can provide significant benefits at a fraction of the cost.
I explore all four levels, detailing the use case for each and pinpointing where the complexity begins to escalate. Check it out here:
