NAME

AnyEvent::Redis - Non-blocking Redis client

SYNOPSIS

  use AnyEvent::Redis;

  my $redis = AnyEvent::Redis->new(
      host => '127.0.0.1',
      port => 6379,
      on_error => sub { warn @_ },
  );

  # callback based
  $redis->set( 'foo'=> 'bar', sub { warn "SET!" } );
  $redis->get( 'foo', sub { my $value = shift } );

  my ($key, $value) = ('list_key', 123);
  $redis->lpush( $key, $value );
  $redis->lpop( $key, sub { my $value = shift });

  # condvar based
  my $cv = $redis->lpop( $key );
  $cv->cb(sub { my $value = $_[0]->recv });

DESCRIPTION

AnyEvent::Redis is a non-blocking Redis client using AnyEvent.

METHODS

All methods supported by your version of Redis should be supported.

Normal commands

There are two alternative approaches for handling results from commands.

the AnyEvent::CondVar manpage based:

  my $cv = $redis->command(
    # arguments to command
  );

  $cv->cb(sub {
    my($cv) = @_;
    my($result, $err) = $cv->recv
  });

Callback:

  $redis->command(
    # arguments,
    sub {
      my($result, $err) = @_;
    });

(Callback is a wrapper around the $cv approach.)

Subscriptions

The subscription methods (subscribe and psubscribe) must be used with a callback:

  my $cv = $redis->subscribe("test", sub {
    my($message, $channel[, $actual_channel]) = @_;
    # ($actual_channel is provided for pattern subscriptions.)
  });

The $cv condition will be met on unsubscribing from the channel.

Due to limitations of the Redis protocol the only valid commands on a connection with an active subscription are subscribe and unsubscribe commands.

Common methods

get
set
hset
hget
lpush
lpop

The Redis command reference (http://code.google.com/p/redis/wiki/CommandReference) lists all commands Redis supports.

REQUIREMENTS

This requires Redis >= 1.2.
