> Today, if a user happens to do something like a large multi-put, they can get
> through request throttling (e.g. it is one request) but still crash a region
> server with a garbage storm. We have seen regionservers hit this issue and it
> is silent and deadly. The RS will report nothing more than a mysterious
> garbage collection and exit out.
> Ideally, we could report a large multi-* request before starting it, in case
> it happens to be deadly. Knowing the client, user and how many rows are
> affected would be a good start to tracking down painful users.
