      Description

      On MongoS:

      • setDefaultRWConcern - passes through to the same command on the config server
      • getDefaultRWConcern - passes through to the same command on the config server by default; if inMemory requested, then returns the locally cached value

      On Config Server or Plain Replica Set (not a shard):

      • setDefaultRWConcern - persists to disk
      • getDefaultRWConcern - by default returns what's persisted on disk; if inMemory requested, then returns the locally cached value

      On Shards:

      • setDefaultRWConcern - should error, because it must never be called directly
      • getDefaultRWConcern - should error, because it must never be called directly
