Cache Write Through or tiering/grading


Is there a way to inform/influence the cache to not cache certain documents, by setting some flag or by any other means?

If data is greater than memory, then couchbase will cache based on LRU/MRU and accordingly evict items. Our application writes an item in the couchbase bucket and obviously that item stays in the cache. But that item may not be required in near future. And hence, is there a way to inform the cache to write that document to disk and then evict it from cache allowing more room for other documents that are likely to be required in near future?
