Cache::Memcached::Fast 0.14を以前のketama algorithmにも対応させる
ketamaの分散を改善するために、全バージョンとアルゴリズムの互換性がなくなったことで有名なCache::Memcache::Fast 0.14ですが以前のアルゴリズムへも対応できるようにpatchつくってみました。
使い方
my $memcached = Cache::Memcached::Fast->new({ servers => [qw/127.0.0.1:11222 127.0.0.1:11223/], old_ketama_algo => 1, ketama_points => 150, });
