CHI::Driver::Memory - In-process memory based cache
version 0.54
use CHI; my $hash = {}; my $cache = CHI->new( driver => 'Memory', datastore => $hash ); my $cache = CHI->new( driver => 'Memory', global => 1 );
This cache driver stores data on a per-process basis. This is the fastest of the cache implementations, but data can not be shared between processes. Data will remain in the cache until cleared, expired, or the process dies.
To maintain the same semantics as other caches, references to data structures are deep-copied on set and get. Thus, modifications to the original data structure will not affect the data structure stored in the cache, and vica versa. See CHI::Driver::RawMemory for a faster memory cache that sacrifices this behavior.
When using this driver, the following options can be passed to CHI->new() in addition to the CHI. One of datastore or global must be specified, or else a warning (possibly an error eventually) will be thrown.
A reference to a hash to be used for storage. Within the hash, each namespace is used as a key to a second-level hash. This hash may be passed to multiple CHI::Driver::Memory constructors.
Use a standard global datastore. Multiple caches created with this flag will see the same data. Before 0.21, this was the default behavior; now it must be specified explicitly (to avoid accidentally sharing the same datastore in unrelated code).
For CHI/SIZE AWARENESS caches, this driver implements an 'LRU' policy, which discards the least recently used items first. This is the default policy.
