Say you have a bunch of solr servers that index new data, and then some replica/"slave" setup that snappulls from the master on a cron or some schedule. Live internet facing queries hit the replica, not the master, as indexes/commits on the master slow down queries. But even the query-only solr installs need to "snap-install" every so often, triggering a commit, and there is a slowdown in queries when this happens. Measured avg QTimes during normal times are 400ms, during commit/snapinstall times they dip into the seconds. Say in the 5m between snappulls 1000 documents have been updated/deleted/added.
How do people mitigate the effect of the commit on replica query instances?
