This software creates a memory cache object that represents a single row from a database table. It helps improve performance by reducing the number of database queries needed. The object is stored in computer memory for fast access.
Rose::DB::Object::Cached is a Perl module that provides a memory cached object representation of a single row in a database table. This software is a subclass of Rose::DB::Object and is backed by a write-through memory cache. The advantage of this is that whenever an object is loaded from or saved to the database, it is cached in memory. Any subsequent attempt to load an object of the same class with the same primary key or unique key value(s) will give you the cached object instead of loading from the database.
The package Category is a perfect illustration of how this software works. It is specified in the synopsis and has been used to demonstrate the process. This means that all modifications made to an object will also modify all other objects in memory that have the same primary key. This emphasizes the efficiency of this software as it saves the stress of repeatedly loading category information in a long-running process.
The memory cache supports time-based expiration, and it can be cleared for an individual object or all objects of the same class. The clear_object_cache and cached_objects_expire_in methods provide more information on how this can be achieved.
This software is ideal for encapsulating "read-only" rows or other data that are updated infrequently. There is support for simple time-based cache expiration, and the methods that are overridden or behaviorally modified are documented in the Rose::DB::Object documentation for better understanding.
