📛 NAME

DBI::Util::CacheMemory - a very fast but very minimal subset of Cache::Memory

🚀 Quick Reference

Use Case	Command	Description
Create a cache	my $cache = DBI::Util::CacheMemory->new(namespace => 'mycache')	Create a new cache instance with a namespace
Store a value	$cache->set('key', 'value')	Store a value indefinitely (no expiry support)
Check if key exists	$cache->exists('key')	Returns true if key exists
Remove a key	$cache->remove('key')	Remove a specific key
Get count of keys	$cache->count()	Return number of keys in cache
Clear all entries	$cache->clear()	Remove all entries from the cache
Purge (same as clear)	$cache->purge()	Alias for clear, deletes everything in namespace

📝 DESCRIPTION

Like Cache::Memory (part of the Cache distribution) but doesn't support any fancy features.

This module aims to be a very fast compatible strict sub-set for simple cases, such as basic client-side caching for DBD::Gofer.

Like Cache::Memory, and other caches in the Cache and Cache::Cache distributions, the data will remain in the cache until cleared, it expires, or the process dies. The cache object simply going out of scope will not destroy the data.
