> Right now the multiplexing channel selector treats all channels as required channels. There should be a simple provision where some channel can be marked optional so that a failure in publishing the event to that particular channel does not cause the entire request to fail. For example, the following configuration:
> agent.sources.foo.selector.mapping.foo = ch1 ch2
> agent.sources.foo.selector.mapping.bar = ch2 ch3
> agent.sources.foo.selector.optional.channels = ch2
> Would imply that for mapping value "foo", ch1 is a required channel whereas ch2 is an optional channel. Similarly, for mapping "bar', ch3 is a required channel but ch2 is optional.
