Smart caching for nameko using evenlet to refresh cached items
asynchronously
Cacheback is an extensible caching library that refreshes stale cache items
asynchronously using nameko EventDispatcher. The key idea being that it’s
better to serve a stale item (and populate the cache asynchronously) than
block the response process in order to populate the cache synchronously.
A corollary of this technique is that cache stampedes can be easily
avoided, avoiding sudden surges of expensive reads when cached items
becomes stale.
nameko-cacheback provides a decorator for simple usage.
