Class: Puppet::Indirector::Msgpack

Inherits:
Terminus show all
Defined in:
lib/puppet/indirector/msgpack.rb

Overview

The base class for MessagePack indirection terminus implementations.

This should generally be preferred to the PSON base for any future implementations, since it is ~ 30 times faster
