- Implemented scoring for DRA-backed extended resources. ([#134058](https://github.com/kubernetes/kubernetes/pull/134058), [@bart0sh](https://github.com/bart0sh)) [SIG Node, Scheduling and Testing]

- DRA: scheduling pods is up to 16x faster, depending on the scenario. Scheduling throughput depends a lot on cluster utilization. It is higher for lightly loaded clusters with free resources and gets lower when the cluster utilization increases.

- `volatile` for status flags
- Synchronized blocks for critical sections
- Thread-local storage via `CrawlingParameterUtil`

**Resource Management**:
- `AutoCloseable` throughout
- `DeferredFileOutputStream` for large responses (temp files for >1MB)
- Connection pooling with limits
- Background temp file deletion via `FileUtil.deleteInBackground()`

**Fault Tolerance**:

 * <li>Default values for crawling and indexing operations</li>
 * <li>User agent strings and patterns for web crawling</li>
 * <li>Status constants for job execution and system states</li>
 * <li>Field names and keys used throughout the application</li>
 * <li>Date/time format patterns</li>
 * <li>Authentication type identifiers</li>
 * <li>Reserved words and regex patterns for query processing</li>
