This will use the optimized rwmutex from SERVER-86656 to create reader-optimized hash-tables for scenarios where the hash-table is not expected to change frequently, but the values are. For synchronizing values, we can either use AtomicWord, or the hazard pointer primitive from SERVER-86657.
This will be helpful for, and should be adopted by, the following:
- Tenant migration access blockers (
SERVER-89009) - Collection sharding state (
SERVER-89434) - API version metrics (
SERVER-88968) - Top (
SERVER-89638)
