> We have a situation where each region server is loaded with 100+ regions,
> most of them in the same table. During a long upload of webpages, each
> memcache gets filled near equally fast so that the global memcache limit is
> usually triggered before the max memcache size. Since that emergency flush
> does not trigger compactions, the number of store files just keeps growing
> until it fails on all kinds of errors.
> We need a better story for this as this is a "normal" situation.
