Cassandra Driver VS zeitwerk

A gem que vamos utilizar para comunicar com o ScyllaDB se chama cassandra-driver, infelizmente ela exige bibliotecas de sistema relacionadas ao banco de dados cassandra para serem instaladas, a forma mais simples de ter essas bibliotecas instaladas é instalar o próprio cassandra na maquina:

Second, I suggest using zeitwerk gem to manage the constants like classes and modules via organizing the files. I'm going to explain why.

It would be interesting to see a comparison to Zeitwerk[1]

Zeitwerk also supports reloading and is near enough a standard for Ruby.

To setup it's pretty simple, you just need to create a file inside bin/console and require all the files you want to use on a REPL, most of the times we use gems like zeitwerk to provide the auto requiring, but if you want to do it manually, refer to the example below:

zeitwerk

Zeitwerk takes a directory and makes every file underneath it available to load. The convention is that every new sub-directory is a new module, and every file defines a class with the same name as the file.

There is a gem that does that used by Rails and multiple other gems:

It is pretty easy to set it up in any Ruby project.

I actually prefer auto-loading, which lets you iterate through a package manager much easier/faster - PHP iterated through PSR-0[0] before landing on PSR-4[1], and you can always build your own (which is what most frameworks pre-composer were doing).

With Rails 7 and Zeitwerk, the Ruby community has landed on a very similar auto-loading system as PHP now[2] with constants translating to paths by convention.

If you're working on non-Rails apps and need to deal with loading code, zeitwerk can be used anywhere, unlike the old Rails autoloader. It's also really easy to set up.
