Writing code in a cluster application

In the “Getting Started” tutorial, we wrote the application code directly in the browser. We used the file config.yml to describe HTTP endpoint handlers. This is a convenient and fast way to write code that allows you to use Tarantool as a repository without any additional HTTP service. This functionality is implemented through the cartridge-extensions module. It is also included in the tutorial default application.

However, in Tarantool, you can implement absolutely any business logic on top of a cluster. This Cartridge getting started section covers the cluster roles mechanism and writing a cluster application from scratch.
