The obstacle I'm seeing is that I have a lot of fields which use sorting. Sooner or later this will give an OutOfMem-error since the field-cache grows too large. Am i correct in assuming that implementing for instance a EHCache with flush-to-disk would solve this issue? (With a tradeoff for performance of course)
Moreover, when warming readers with the patch, thus having 2 reader open at the same time (I am using solr searchers btw, but I guess these use the same underlying lucene-code, I'll have to check) can these 2 readers shares the same fieldcache and thus eliminate the required double memory while warming?
