Re: [External] Re: Newbie question using Kafka Producers in Web apps

["Tauzell, Dave" <Da...@surescripts.com>]

We are using both and leaning towards a web service fronting Kafka because it gives us the ability to centralize other logic.   That said, I don't think the webservice will be much more "stable" and you'll need to consider what to do with your audit records if the web service call fails.

    I don’t feel it would be a big hit in performance because Kafka works very fast. I think the speed difference would be negligible. Why are you worried about stability? I’m just curious because it doesn’t seem like it would be unstable, but maybe it would be a bit overkill for one app and some decoupling might make sense.
