### OpenSearch Integration

```java
// Add OpenSearch dependency and configure
container.singleton("opensearchDataService", OpenSearchDataService.class, service -> {
    service.setIndexName("crawler-data");
    service.setHostname("localhost");
    service.setPort(9200);
});
```

## Performance Tuning

### Thread Configuration

```java
// Optimize thread pool settings
