SYNOPSIS

            

              
              
use Redis;
use Redis::Transaction qw/multi_exec watch_multi_exec/;
# atomically increment foo and bar. It will execute following commands typically.
# > MULTI
# > INCR foo
# > INCR bar
# > EXEC
multi_exec Redis->new, 10, sub {
    my $redis = shift;
    $redis->incr('foo');
    $redis->incr('bar');
};
# atomically increment the value of a key by 1 (let's suppose Redis doesn't have INCR).
# It will execute following commands typically.
# > WATCH mykey
# > GET mykey
# > MULTI
# > SET mykey, 1
# > EXEC
watch_multi_exec Redis->new, ['mykey'], 10, sub {
    my $redis = shift;
    return $redis->get('mykey');
}, sub {
    my ($redis, $value) = @_;
    $redis->set('mykey', $value + 1);
};

FUNCTIONS

multi_exec($redis:Redis, $retry_count:Int, $code:Code)
