DBI::Util::CacheMemory(3) User Contributed Perl Documentation DBI::Util::CacheMemory(3)

# [NAME](#NAME)

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

# [DESCRIPTION](#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.

# [METHODS WITH CHANGES](#METHODS_WITH_CHANGES)
