Course of Projections with Kafka

💸 First lesson available without registration 💸

If we want our infrastructure to scale, we need to apply projections.

But this has a problem. For example, to do the projection of a product, we have to listen to:

• ⭐ ProductCreated: To start the projection.
• 📚 ProductRenamed: Every time the name is modified, we update it.
• 🖼️ ProductImageAdded: Add each new image of the product.
• …: All the mutations that a product has basically.

This means we have to write a lot of code to maintain this projection that does not add value. And the worst part is that every team that wants its projection has to do the same.

Fortunately, there is an alternative, and that’s what we explain in the course. You can use Kafka combined with Compacted Topics to greatly reduce all the boilerplate required to have our projections.
