I have a multicore solr with a lot of cores that contains a lot of data (~50M
documents), but are rarely used.
Can i load a core from configuration, but have keep it in sleep mode, where
is has all the configuration available, but it hardly consumes resources,
and based on a query or an update, it will "come to life"?
Thanks

Well, that'll be kinda self-defeating. The whole point of auto-warming
is to fill up the caches, consuming memory. Without that, searches
will be slow. So the idea of using minimal resources is really
antithetical to having these in-memory structures filled up.

You can try configuring minimal caches & etc. Or just give it
lots of memory and count on your OS to swap the pages out
if the particular core doesn't get used.

My random searches can be a bit slow on startup, so i still would like to
get that lazy load but have more cores available.
I'm actually trying now the LotsOfCores way of handling things.
Had to work a bit to get the patch suitable for 3.5 but it seems to be
doing what i need.
