NAME

Redis::Cluster::Fast - A fast perl binding for Redis Cluster

SYNOPSIS

use Redis::Cluster::Fast;

my $redis = Redis::Cluster::Fast->new(
    startup_nodes => [
        'localhost:9000',
        'localhost:9001',
        'localhost:9002',
        'localhost:9003',
        'localhost:9004',
        'localhost:9005',
    ],
    connect_timeout => 0.05,
    command_timeout => 0.05,
    max_retry_count => 10,
);

$redis->set('test', 123);

# '123'
my $str = $redis->get('test');

$redis->mset('{my}foo', 'hoge', '{my}bar', 'fuga');

# get as array-ref
my $array_ref = $redis->mget('{my}foo', '{my}bar');
# get as array
my @array = $redis->mget('{my}foo', '{my}bar');

$redis->hset('mymap', 'field1', 'Hello');
$redis->hset('mymap', 'field2', 'ByeBye');

# get as hash-ref
my $hash_ref = { $redis->hgetall('mymap') };
# get as hash
my %hash = $redis->hgetall('mymap');

DESCRIPTION

Redis::Cluster::Fast is like Redis::Fast but support Redis Cluster by hiredis-cluster.

To build and use this module you need libevent-dev >= 2.x is installed on your system.

Recommend Redis 6 or higher.

Since Redis 6, it supports new version of Redis serialization protocol, RESP3. This client start to connect using RESP2 and currently it has no option to upgrade all connections to RESP3.
