pool.prefetch

Prefetch pool metadata (DDT and BRT) into ARC.

Loads both the Deduplication Table (DDT) and Block Reference Table (BRT) into the ARC to reduce latency of subsequent operations. This is useful for warming up the cache before performing operations that benefit from having this metadata readily available.

The DDT tracks deduplication metadata, while the BRT tracks block cloning metadata used for efficient copy-on-write operations.

This method is a job.
