    Description

      Currently each WiredTiger session has its own random number generator, and they use the same seed. This is not ideal, and makes it very difficult to describe the guarantees of random operations such as aggregation's $sample (which can use a random cursor).

      I'm not sure what the best way is to fix it, but I think we should do something about it.
