I am looking at using memchached for caching blob objects and flush them
after a while. My use case is that users may save lots of times and instead
of persisting every save I would save the data only at logical point to the
database or if there was no activity for n seconds then read from memcached
and flush it to the database. Can someone please give me pointers on how to
design this scenario? For instance how to efficiently sync memcached with
database such that it takes care of stale data, flushing every n seconds
etc.
