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

new
All options except "namespace" are ignored.

set
Doesn't support expiry.

purge
Same as clear() - deletes everything in the namespace. If it's not listed above, it's not supported.
