NAME

Class::DBI::Lite::CacheManager::InMemory - Cache in RAM.

SYNOPSIS

package app::user;

use strict;
use warnings 'all';
use base 'app::model';
use Class::DBI::Lite::CacheManager::InMemory;

__PACKAGE__->set_up_table('users');

__PACKAGE__->set_cache(
  Class::DBI::Lite::CacheManager::Memcached->new(
    lifetime        => '30s',
    class           => __PACKAGE__,
    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     => 'alice@wonderland.net',
  password  => 'whiterabbit',
);

...later - within 30 seconds...

# This won't hit the database - the result will come from the cache instead:
my ($user) = app::user->search(
  email     => 'alice@wonderland.net',
  password  => 'whiterabbit',
);

A create, update or delete invalidates the cache:

$user->delete; # Cache is emptied now.

DESCRIPTION

Class::DBI::Lite::CacheManager::InMemory will store the results of searches in RAM for a specific length of time. This is helpful if you find that your application's performance is suffering because of oft-repeated queries.

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.
