// Arenas are useful for improving efficiency as they may be freed back to

### Generate a job yaml
```
mc batch generate alias/ replicate
```

### Start the batch job (returns back the JID)
```
mc batch start alias/ ./replicate.yaml
Successfully start 'replicate' job `E24HH4nNMcgY5taynaPfxu` on '2022-09-26 17:19:06.296974771 -0700 PDT'

For gradual adoption, enable checks project-by-project.
Do not rely on `@NullMarked` annotations.
Only enable checks for a project if all its dependencies have checks enabled, in order to avoid back-and-forth when refining the annotations.

Avoid writing the so-called `PolyNull` or `ParametricNull` methods (where nullability of the result depends on the nullability of the type argument).

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference so you can come back and see exactly what you need.

## Run the code { #run-the-code }

All the code blocks can be copied and used directly (they are actually tested Python files).
