## Other Return Type Annotations { #other-return-type-annotations }

There might be cases where you return something that is not a valid Pydantic field and you annotate it in the function, only to get the support provided by tooling (the editor, mypy, etc).

### There are no limits on how many server pools can be combined

```
minio server http://host{1...32}/export{1...32} http://host{1...12}/export{1...12}
```

In above example there are two server pools

- 32 * 32 = 1024 drives pool1
- 12 * 12 = 144 drives pool2

    @Override
    public int hashCode() {
      return interner.hashCode();
    }

    @Override
    public boolean equals(@Nullable Object other) {
      if (other instanceof InternerFunction) {
        InternerFunction<?> that = (InternerFunction<?>) other;
        return interner.equals(that.interner);
      }

      return false;
    }
  }

```

### Things to know

- Fields such as `version` and `pools` are mandatory, however all other fields are optional.
- Each pool expects a minimum of 2 nodes per pool, and unique non-repeating hosts for each argument.
- Each pool expects each host in this pool has the same number of drives specified as any other host.
- Mixing `local-path` and `distributed-path` is not allowed, doing so would cause MinIO to refuse starting the server.
