After we set up AboutUs’s search feature our (awesome) sysadmin wanted a redundant setup. He doesn’t like having to cancel his weekend if a box goes down. We talked about running an instance of HAProxy on all our app servers to load balance between two Sphinx servers, but that seemed heavy handed.
It turned out to be really easy to add this functionality to ThinkingSphinx (and the Riddle client it uses to talk to Sphinx).
