Data::ObjectDriver::Driver::Cache::Apache(3pm) User Contributed Perl Documentation Data::ObjectDriver::Driver::Cache::Apache(3pm) NAME
Data::ObjectDriver::Driver::Cache::Apache - object driver for caching objects in Apache's request space SYNOPSIS
package MyObject; use base qw( Data::ObjectDriver::BaseObject ); __PACKAGE__->install_properties({ ... driver => Data::ObjectDriver::Driver::Cache::Apache->new( fallback => Data::ObjectDriver::Driver::Cache::Memcached->new( cache => Cache::Memcached->new({ servers => @MEMCACHED_SERVERS }), fallback => Data::ObjectDriver::Driver::DBI->new( @$DBI_INFO ), ), ), ... }); 1; DESCRIPTION
Data::ObjectDriver::Driver::Cache::Apache provides automatic caching of retrieved objects in the per-request memory space of your Apache mod_perl processes, when used in conjunction with your actual object driver. It can be used to provide even faster results over memcached when requesting objects that have already been requested during the same request by some other part of your application, at the cost of the memory necessary to store the objects. If your models can be used in an Apache mod_perl application as well as another context such as a command line shell, consider replacing the Apache layer of your caching with a "Data::ObjectDriver::Driver::Cache::RAM" layer when Apache is not available. See Data::ObjectDriver::Driver::Cache::Apache. USAGE
o Data::ObjectDriver::Driver::Cache::Apache->new(%params) Required members of %params are: o "fallback" The "Data::ObjectDriver" object driver from which to request objects that are not found in the Apache process cache. DIAGNOSTICS
The Apache driver provides integration with the "Data::ObjectDriver" debug and profiling systems. As these systems are designed around SQL queries, synthetic queries are logged to represent caching operations. The operations generated by this driver are: o "APACHECACHE_GET ?" Retrieve an object. The argument is the cache key for the requested object. o "APACHECACHE_ADD ?,?" Add an object to the cache. The arguments are the cache key for the object and the flattened representation of the object to cache. o "APACHECACHE_SET ?,?" Put an object in the cache. The arguments are the cache key for the object and the flattened representation of the object to cache. o "APACHECACHE_DELETE ?" Remove an object from the cache. The argument is the cache key for the object to invalidate. SEE ALSO

CHI::Driver::Memcached(3pm) User Contributed Perl Documentation CHI::Driver::Memcached(3pm) NAME
CHI::Driver::Memcached -- Distributed cache via memcached (memory cache daemon) VERSION
version 0.14 SYNOPSIS
use CHI; my $cache = CHI->new( driver => 'Memcached', # or 'Memcached::Fast', or 'Memcached::libmemcached' namespace => 'products', servers => [ "10.0.0.15:11211", "10.0.0.15:11212", "/var/sock/memcached", "10.0.0.17:11211", [ "10.0.0.17:11211", 3 ] ], debug => 0, compress_threshold => 10_000, ); DESCRIPTION
A CHI driver that uses Cache::Memcached to store data in the specified memcached server(s). CHI::Driver::Memcached::Fast and CHI::Driver::Memcached::libmemcached are also available as part of this distribution. They work with other Memcached clients and support a similar feature set. Documentation for all three modules is presented below. CONSTRUCTOR OPTIONS
Namespace, appended with ":", is passed along to the Cached::Memcached::* constructor, along with any constructor options not recognized by CHI - for example servers, compress_threshold and debug. If you need more control over the options passed to Cache::Memcached::*, you may specify a hash directly in "memd_params". METHODS
Besides the standard CHI methods: memd Returns a handle to the underlying Cache::Memcached::* object. You can use this to call memcached-specific methods that are not supported by the general API, e.g. $self->memd->incr("key"); my $stats = $self->memd->stats(); UNSUPPORTED METHODS
These standard CHI methods cannot currently be supported by memcached, chiefly because there is no way to get a list of stored keys. dump_as_hash clear get_keys get_namespaces is_empty purge SUPPORT AND DOCUMENTATION
Questions and feedback are welcome, and should be directed to the perl-cache mailing list: http://groups.google.com/group/perl-cache-discuss Bugs and feature requests will be tracked at RT: http://rt.cpan.org/NoAuth/Bugs.html?Dist=CHI-Driver-Memcached The latest source code can be browsed and fetched at: http://github.com/jonswar/perl-chi-driver-memcached/tree/master git clone git://github.com/jonswar/perl-chi-driver-memcached.git AUTHOR
