Class::DBI::Lite::CacheManager::Memcached - Cache via memcached.
package app::user; use strict; use warnings 'all'; use base 'app::model'; use Class::DBI::Lite::CacheManager::Memcached; __PACKAGE__->set_up_table('users'); __PACKAGE__->set_cache( Class::DBI::Lite::CacheManager::Memcached->new( lifetime => '30s', class => __PACKAGE__, servers => ['127.0.0.1:11211'], do_cache_search => 1, ) ); __PACKAGE__->cache->cache_searches_containing(qw( email password ));
Then, someplace else...
# This will be cached... my ($user) = app::user->search( email => 'firstname.lastname@example.org', password => 'whiterabbit', );
# This won't hit the database - the result will come from the cache instead: my ($user) = app::user->search( email => 'email@example.com', password => 'whiterabbit', );
A create, update or delete invalidates the cache:
$user->delete; # Cache is emptied now.
Class::DBI::Lite::CacheManager::Memcached uses Cache::Memcached to temporarily store the results of (presumably) frequent database searches for faster lookup.
So, if your data requirements are such that you find objects of a specific class are getting called up frequently enough to warrant caching - you can now do that on a per-class basis.
You can even specify the kinds of search queries that should be cached.
You can specify the length of time that cached data should be available.
NOTE: More documentation and complete examples TBD.
