Related Tracker: https://tracker.ceph.com/issues/63191 +* CephFS: CephFS mirroring now utilizes a multi-threaded architecture to improve synchronization + performance. The workload is split into two distinct thread pools: a crawler thread pool, which + manages snapshot crawl and a data synchronization thread pool, which handles concurrent file + transfers. Users can fine-tune these operations using configuration parameters: + cephfs_mirror_max_concurrent_directory_syncs (controlling the number of concurrent snapshots being crawled) + and cephfs_mirror_max_concurrent_data_sync_threads (controlling the total threads available for data sync). + For more information, see https://tracker.ceph.com/issues/73452 >=20.0.0
