[erlang-questions] pub-sub server implementation detail question.

[Huseyin Yilmaz]

Hi
I was checking the source code for kraken (https://github.com/Asana/kraken).
I realized that this pub sub server was implemented by using
gen_server behavior. But when I think about a pub-sub server, I would
definitely choose to use gen_event behavior  I think gen_event behavior
solves this kind of problems very well. I was wondering if there is a
reason for not using gen_event behavior for pub-sub server that I am not
aware of?
