Isaac Hebsh commented on SOLR-4449:
-----------------------------------
And, as i asked in the duplicated issue SOLR-5092, the code contains a comment
that says it's important to "use the same replica for all phases of a
distributed request."
I don't think it's important, because it might happen even without this plugin,
if one replica goes down between two phases of the request.
Do you have any thoughts/conclusions about this?

> Add the ability to configure the built-in solr load balancer such that it
> submits a backup request to the next server in the list if the initial
> request takes too long. Employing such an algorithm could improve the latency
> of the 9xth percentile albeit at the expense of increasing overall load due
> to additional requests.
