## 2. Distributed Deployment

To host multiple tenants in a distributed environment, run several distributed MinIO Server instances concurrently.

### 2.1 Host Multiple Tenants on Multiple Drives (Erasure Code)

Use the following commands to host 3 tenants on a 4-node distributed configuration:

```sh
export MINIO_ROOT_USER=<TENANT1_ACCESS_KEY>

 * and DI container integration.
 *
 * <p>Thread Safety: This class is thread-safe. Each evaluate() call creates
 * a new GroovyShell instance to ensure thread isolation.</p>
 *
 * <p>Resource Management: GroovyClassLoader instances are properly managed
 * and cleaned up after script evaluation to prevent memory leaks.</p>
 */
public class GroovyEngine extends AbstractScriptEngine {

   * throws an {@link IllegalArgumentException} when presented with duplicate elements instead of
   * collapsing them to a single element or including duplicate instances in the collection.
