Jifty::DBI::Record::Cachable
records with caching behavior

Jifty::DBI::Record::Cachable - records with caching behavior


NAME

Jifty::DBI::Record::Cachable - records with caching behavior


SYNOPSIS


  package Myrecord;

  use base qw/Jifty::DBI::Record::Cachable/;


DESCRIPTION

This module subclasses the main the Jifty::DBI::Record manpage package to add a caching layer.

The public interface remains the same, except that records which have been loaded in the last few seconds may be reused by subsequent fetch or load methods without retrieving them from the database.


METHODS

flush_cache

This class method flushes the _global_ Jifty::DBI::Record::Cachable cache. All caches are immediately expired.

_flush_key_cache

Blow away this record type's key cache

load_from_hash

Overrides the implementation from the Jifty::DBI::Record manpage to add caching.

load_by_cols

Overrides the implementation from the Jifty::DBI::Record manpage to add caching.

_cache_config

You can override this method to change the duration of the caching from the default of 5 seconds.

For example, to cache records for up to 30 seconds, add the following method to your class:


  sub _cache_config {

      { 'cache_for_sec' => 30 }

  }
