NAME

Data::Throttler::Memcached - Memcached-Based Data::Throttler

CONTENTS

SYNOPSIS



  my $t = Data::Throttler::Memcached->new(
    max_items => 10,
    interval  => 60,
    cache     => {
      data  => 127.0.0.1:11211, # optional
    }
  );
 
  $t->try_push( foo );
  $t->try_push( key => foo );



DESCRIPTION

Data::Throttler does a good job throttling data for you, but unfortunately it’s not distributed — that is, since the storage is in memory, if you have a system with multiple hosts, throttling will be done individually on each host.

To workaround this limitation, Data::Throttler::Memcached uses Cache::Memcached::Managed to store the actual data.

CAVEATS

There’s no locking mechanism when checking/incrementing counts. This means that each process could possibly overwrite another’s value — but since throttling is something that isn’t exact, I’m not considering this to be such a big issue.

We may in the future work around this problem by utilizing distributed locks like KeyedMutex. Patches welcome.

METHODS

    new

Creates a new instance of Data::Throttler::Memcached. Accepts the same arguments as Data::Throttler, plus the cache argument.

The cache argument must be a hashref, which contains the arguments passed to the cache backend. For example, if you wanted to change the data server, you can specify it like so:



  cache => {
    data => my.data.host:11211
  }
