- MinIO also supports expansion of existing clusters in server pools. Each pool is a self contained entity with same SLA's (read/write quorum) for each object as original cluster. By using the existing namespace for lookup validation MinIO ensures conflicting objects are not created. When no such object exists then MinIO simply uses the least used pool to place new objects.

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

# MinIO Pull Request Guidelines

These guidelines ensure high-quality commits in MinIO’s GitHub repositories, maintaining 
a clear, valuable commit history for our open-source projects. They apply to all contributors, 
fostering efficient reviews and robust code.

## Why Pull Requests?

Pull Requests (PRs) drive quality in MinIO’s codebase by:
- Enabling peer review without pair programming.
- Documenting changes for future reference.

        // and the credentials. The delegate is tested implicitly by calling super's methods.
        // We can directly test getCredentials() to ensure it returns the initial credentials.
        assertEquals(mockCredentials, wrapper.getCredentials(), "Initial credentials should be set by constructor");
    }
