Virgil Chereches created an issue   Hiera / HI-466 Added memcache caching method for Hiera backends Issue Type: New Feature Affects Versions: HI 3.0.2 Assignee: Virgil Chereches Components: Community Created: 2015/09/06 11:52 PM Priority: Normal Reporter: Virgil Chereches I found very useful to have a memcache cache (similar with Filecache class) for custom hiera backends. It seems that using memcache decreases the catalog compilation time three times in our case. Since this is a useful feature across backends, I think that it should be put in the hiera library. That's why I'm proposing this PR. On the other hand, the dependency on ruby Dalli class should be evaluated - no official RPM exists for RH and CentOS, only for Fedora and Ubuntu. Several usage information: The following code should be specified in the custom backend: in initialize method: @cache = cache || Memcache.new(@servers) (of course, the @servers array should be taken from the configuration file during initialization) in lookup method: @cache.fetch(key) { search_method(key) } where key is the lookup key (or something obtained from lookup key) and search_method is the expensive code called for finding the information pertaining to lookup key.
