Is there MGET analog for Redis hashes?

Question

I\'m planning to start using hashes insead of regular keys. But I can\'t find any information about multi get for hash-keys in Redis wiki. Is this kind of command is support

There is no command to do it on one shot, but there is a way to do it "nicely", using a list (or sorted set) where you would store you hashKeys, and then retrieve them as bulk using multi.

In PHP:

$redis->zAdd("myHashzSet", 1, "myHashKey:1");
$redis->zAdd("myHashzSet", 2, "myHashKey:2");
$redis->zAdd("myHashzSet", 3, "myHashKey:3");

$members = $redis->zRange("myHashzSet", 0, -1);
$redis->multi();
foreach($members as $hashKey) {
    $redis->hGetAll($hashKey);
}
$results = $redis->exec();

I recommand using a sorted set, where you use the score as an ID for your hash, it allows to take advantages of all score based command.
