Hawkular Metrics is a reactive application and calls to a blocking API should be avoided as much as possible. The Openshift integration library had a servlet filter mechanism to authenticate users. The filter code used the JDK's HTTP client to call Kubernetes' master server. While this was alright has a first implementation (in order to provide the feature as quickly as possible), it is a serious limitation to reach our performance goals. There were two problems to tackle: 1. choose an async HTTP client API 2. make the filter code asynchronous For the HTTP client, I considered a few options: Netty, vert.x, Undertow. I picked undertow because it does not add a new dependency, we can reuse the io threads (instead of creating yet another thread pool). The downside is that the Undertow client API is low-level (no pool implementation) and not well documented. For the filter code, my first try was to use servlet async API from the filter. But RestEasy throws an exception because it wants start the async exchange itself. I wrote to the resteasy-user list but got no reply. And even if we had a fix, we would have to wait for a new RestEasy and Wildfly release. So I wrote an Undertow extension which is executed in io threads *before* the servlet handler is involved. The implementation consists in pooling Undertow HTTP client connections and filering the Metrics client requests (only dispatch to the servlet handler if the user is authenticated). While working on the implementation I had to find a way to share the MetricsRegistry between the webapp code and the authenticator code. So there's a MetricsRegistry provider class in core-util now. Also, I enhanced the Gatling scenario file to support multiple authentication mechanisms (none, Hawkular integration, Openshift htpasswd file, Openshift token). I took the opportunity to document the scenario options in the project README. Note that performance enhancements will be more visible in environments where Kubernetes reponse time is minimal.
