NAME

Cache::Ref::CAR

SYNOPSIS

    my $c = Cache::Ref::CAR->new(
        size => $n,
    );

DESCRIPTION

This algorithm is an implementation of http://www.almaden.ibm.com/cs/people/dmodha/clockfast.pdf.

See also Cache::Ref::CART which is probably more appropriate for random access work loads.

CAR balances between an MFU like policy and an MRU like policy, automatically tuning itself as the workload varies.

NAME

Cache::Ref::CAR - CLOCK with Adaptive Replacement

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.
