[Design of JBossCache] - Re: Redesigning eviction
by genman
I went down the road of thinking of eviction as also being about invalidation, and created an algorithm for performing timed expiration, but JBoss Cache expiration is really just the lowly task of managing memory.
Anyway, in addition to "when" "which" and "how many" I'd like to see "in what way" added to the list of concerns. Typically, people want to do "page to disk", but I can imagine wanting plain removal, or migration, or compression perhaps. (Background compression would be a neat feature, come to think of it.)
And in terms of invalidation, some sort of general "invalidation" interceptor would be nice to see that checked the validity of the data being fetched. This is likely necessary since the eviction thread might not be work soon enough.
