Description

Rage limiting of accepted connections

Documentation

Policy which governs how to limit the number of accepted connections.

Constructors

Fields

acceptedConnectionsHardLimit :: !Word32
Hard limit of accepted connections.
acceptedConnectionsSoftLimit :: !Word32
Soft limit of accepted connections. If we are above this threshold, we will start rate limiting.
acceptedConnectionsDelay :: !DiffTime
Max delay for limiting accepted connections. We use linear regression starting from 0 at the soft limit up to acceptedConnectionDelay at the hard limit.
