Cache::Ref::CART(3pm) User Contributed Perl Documentation Cache::Ref::CART(3pm)NAME
Cache::Ref::CART - CAR with temporal filtering
SYNOPSIS
my $c = Cache::Ref::CART->new(
size => $n,
);
DESCRIPTION
This algorithm is an extension to Cache::Ref::CAR that has temporal filtering on the upgrading from MRU to MFU pool.
This means that two subsequent accesses to the same key do not automatically make it viable for long term caching, to get upgraded to MFU
status a key must be expired but known in the history.
This is probably the most general purpose caching algorithm.
ATTRIBUTES
size
The size of the live entries.
Note that the cache also remembers this many expired keys, and keeps some metadata about those keys, so for memory usage the overhead
is probably around double what Cache::Ref::LRU requires.
