Aengus Rooney commented on HIVE-16917:
--------------------------------------
Thanks Thejas, discussed this with the team and it was agreed a User+IP
combination would also be beneficial, as multiple apps use the same user for
certain applications. The default thresholds are acceptable, so long as they
are configurable.

> Rogue applications can make HS2 unusable for others by making too many
> connections at a time.
> HS2 should start rejecting the number of connections from a user, after it
> has reached a configurable threshold.
