NAME
AnyEvent::Hiredis - AnyEvent hiredis API
SYNOPSIS
use AnyEvent::Hiredis;
my $redis = AnyEvent::Hiredis->new(
host => '127.0.0.1',
port => 6379,
);
$redis->command( [qw/SET foo bar/], sub { warn "SET!" } );
$redis->command( [qw/GET foo/, sub { my $value = shift } );
$redis->command( [qw/LPUSH listkey value/] );
$redis->command( [qw/LPOP listkey/], sub { my $value = shift } );
# errors
$redis->command( [qw/SOMETHING WRONG/, sub { my $error = $_[1] } );DESCRIPTION
AnyEvent::Hiredis is an AnyEvent Redis API that uses the hiredis C client library (https://github.com/antirez/hiredis).
PERFORMANCE
One reason to consider AnyEvent::Hiredis over its pure Perl counterpart AnyEvent::Redis is performance. Here's a head to head comparison of the two modules running on general purpose hardware:
Rate ae_redis ae_hiredis
AnyEvent::Redis 7590/s -- -89%
AnyEvent::Hiredis 69400/s 814% --Rate here is the number of set operations per second achieved by each module. See bin/compare.pl for details.
METHODS
new
my $redis = Redis->new; # 127.0.0.1:6379
my $redis = Redis->new(server => '192.168.0.1', port => '6379');command
command takes an array ref representing a Redis command and a callback. When the command has completed the callback is executed and passed the result or error.
$redis->command( ['SET', $key, 'foo'], sub {
my ($result, $error) = @_;
$result; # 'OK'
});
$redis->command( ['GET', $key], sub {
my ($result, $error) = @_;
$result; # 'foo'
});If the Redis server replies with an error then $result will be undef and $error will contain the Redis error string. Otherwise $error will be undef.
