AnyEvent::Redis::RipeRedis is a non-blocking Redis client with auto reconnect feature. It supports subscriptions, transactions, has simple API and it faster than AnyEvent::Redis.
Requires Redis 1.2 or higher and any supported event loop.
my $redis = AnyEvent::Redis::RipeRedis->new( host => 'localhost', port => '6379', password => 'your_password', connection_timeout => 5, reconnect => 1, encoding => 'utf8', on_connect => sub { print "Connected\n"; }, on_disconnect => sub { print "Disconnected\n"; } on_error => sub { my $err = shift; warn "$err\n"; }, );
Server hostname (default: 127.0.0.1)
Server port (default: 6379)
Authentication password. If it specified, client sends AUTH command after establishing a connection. If it not specified, you can send AUTH command yourself.
Connection timeout. If after this timeout client could not connect to the server, callback "on_error" will be called.
If this parameter is TRUE, client in case of lost connection will automatically reconnect during executing next command. If this parameter is FALSE, client don't reconnect automaticaly. By default is TRUE.
Will be used to encode strings before sending them to the server and to decode strings after receiving them from the server. If this parameter not specified, encode and decode operations not performed.
This callback will be called when connection will be established
This callback will be called in case of disconnection
This callback will be called if occurred any errors
# Increment $redis->incr( 'foo', { on_done => sub { my $data = shift; print "$data\n"; }, on_error => sub { my $err = shift; warn "$err\n"; }, } ); # Set value $redis->set( 'bar', 'Some string' ); # Get value $redis->get( 'bar', { on_done => sub { my $data = shift; print "$data\n"; }, } ); # Push values for ( my $i = 1; $i <= 3; $i++ ) { $redis->rpush( 'list', "element_$i", { on_done => sub { my $data = shift; print "$data\n"; }, } ); } # Get list of values $redis->lrange( 'list', 0, -1, { on_done => sub { my $data = shift; foreach my $val ( @{ $data } ) { print "$val\n"; } }, on_error => sub { my $err = shift; warn "$err\n"; }, } );
Full list of Redis commands can be found here: http://redis.io/commands
Subscribe to channel by name
$redis->subscribe( qw( ch_foo ch_bar ), { on_done => sub { my $ch_name = shift; my $subs_num = shift; print "Subscribed: $ch_name. Active: $subs_num\n"; }, on_message => sub { my $ch_name = shift; my $msg = shift; print "$ch_name: $msg\n"; }, } );
Subscribe to group of channels by pattern
$redis->psubscribe( qw( info_* err_* ), { on_done => sub { my $ch_pattern = shift; my $subs_num = shift; print "Subscribed: $ch_pattern. Active: $subs_num\n"; }, on_message => sub { my $ch_name = shift; my $msg = shift; my $ch_pattern = shift; print "$ch_name ($ch_pattern): $msg\n"; }, on_error => sub { my $err = shift; warn "$err\n"; }, } );
Unsubscribe from channel by name
$redis->unsubscribe( qw( ch_foo ch_bar ), { on_done => sub { my $ch_name = shift; my $subs_num = shift; print "Unsubscribed: $ch_name. Active: $subs_num\n"; }, on_error => sub { my $err = shift; warn "$err\n"; }, } );
Unsubscribe from group of channels by pattern
$redis->punsubscribe( qw( info_* err_* ), { on_done => sub { my $ch_pattern = shift; my $subs_num = shift; print "Unsubscribed: $ch_pattern. Active: $subs_num\n"; }, on_error => sub { my $err = shift; warn "$err\n"; }, } );
Redis 2.2 and higher support connection via UNIX domain socket. To connect via a UNIX-socket in the parameter "host" you must specify "unix/", and in parameter "port" you must specify the path to the socket.
my $redis = AnyEvent::Redis::RipeRedis->new( host => 'unix/', port => '/tmp/redis.sock', );
