: Subject: Best way to prevent max warmers error Slightly old thread, but i haven't seen any replies...
: We have an application with more 2.5 million docs currently. It is : hosted on a single box with 8 GIG memory. The number of warmers : configured are 4 and Cold-searcher is allowed too. The application is the current example configs suggest 2 ... i can't honestly think of any good reason to have more then that. There is a fairly fundemental trade off question here. the knobs you can adjust are: a) how often new searchers are opened b) how much warming you wnat to do c) how powerful your hardware is if you are getting overlapping searchers, you can either do less warming (and make the first users of those searchers pay an extra cost because of the empty caches) or you can open new searchers less frequently so that the warm time doesn't exceed the frequency, or you can throw hardware at the problem and try speed things up that way. deciding between a, b, and c is't really a technical question so much as a business question. FWIW: There may be a "d) make Solr more efficient" option, and by all means if you find that knob, please let the rest of us know where it is so we can all turn it :) -Hoss
