> Load Balancer backend selection synchronization issue
> -----------------------------------------------------
>
> Key: KNOX-3041
> URL: https://issues.apache.org/jira/browse/KNOX-3041
> Project: Apache Knox
> Issue Type: Bug
> Components: Server
> Reporter: Istvan Toth
> Assignee: Tamás Hanicz
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> I was trying to run a benchmark over Knox, with several Http client instances
> started at the same time on separate threads.
> I found that every single client was directed to the same backend, which was
> saved in the session, so instead of accessing each backend, every request was
> directed to a single one.
> While this was a benchmark/load test tool, any non-interactive client can
> exhibit similar behaviour, defating the point of load balancing.
> Looking at
> org.apache.knox.gateway.ha.dispatch.ConfigurableHADispatch.executeRequestWrapper(HttpUriRequest,
> HttpServletRequest, HttpServletResponse)
> , I think that the sitation could be improved by calling
> haProvider.makeNextActiveURLAvailable BEFORE the request is executed.
> It would be still racy, but the race window would be dramatically smaller,
> running some simple local code, which should be on the microsecond scale,
> instead of performing a full HTTP reqest, which is on on the millisecond
> scale at best.
