Aspire 9 upcoming features 🧵:

First, you'll be able to use Aspire 9 with .NET 8 and .NET 9! It will no longer require a call to dotnet workload install, and instead uses an MSBuild SDK. This should simplify CI/CD integration and getting started immensely! All you need is NuGet!

CQRS = Separate read/write databases?

Not so fast! ❌

This isn't really what CQRS is about.

First, there was the CQS - Command-Query Separation principle.

Here's what CQS is:

- Commands change state, don't return data
- Queries don't change state, return data
- Queries should not have side effects

What? I can't return data from a command?!

Of course, you can - but the intent is different.

I'm not saying you shouldn't be pragmatic.

For example, you insert a new row into the database and return the ID. Perfectly fine.

But what about CQRS?

CQRS stands for Command-Query Responsibility Segregation.

It's an evolution of CQS and works on the architecture level.

Whereas CQS works on the method (or class) level.

It separates the code responsible for handling commands from the code for handling queries.

In other words, you have a logical separation of reads and writes.

You can also extend this with different logical data models.

Here are a few benefits you get with CQRS:

- Complexity management
- Scalability
- Flexibility
- Security

How did we begin associating CQRS with separate read/write databases?

This happens when you take the logical separation of commands and queries and elevate it to physical separation.

There are many flavors of this approach:

- Event sourcing + NoSQL
- SQL + NoSQL
- SQL + Redis

And while it has its benefits, like improving your job security, too much complexity can hurt your project.

So start simple. You can do CQRS with one database.

Apply logical separation of commands and queries.

Only add further complexity if you need to.

Would you use CQRS in your project, or do you view it as over-engineering?
