Config `compress` settings take extensions and mime-types to be compressed.

```bash
~ mc admin config get myminio compression
compression extensions=".txt,.log,.csv,.json,.tar,.xml,.bin" mime_types="text/*,application/json,application/xml"
```

Default config includes most common highly compressible content extensions and mime-types.
