I'll try and get some for you :) > What happens when your cache gets trashed? Do compactions and flushes > go slower? > If you use flashcache-wt flushed and compacted sstables will go to the cache. All reads are cached, so if you compact three sstables into one, you are stuffing your cache with a lot of useless crap and evicting valid blocks (flashcache won't honor any of the hints set with fadvise, as it's a block cache layer and doesn't know of them anyway). If your write rate is low it might work for you. > aj > > > >
