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

Answer 1

If SORT let you use multiple GETs with the -> syntax, and all your hashes had the same fields, you could get them in a bulk reply by putting their names into a set and sorting that.

  SORT names_of_hashes GET *->field1 *->field2 *->field3 *->etc

But it doesn't look like you can do that with the hash access. Plus you'd have to turn the return list back into hashes yourself.

UPDATE: Redis seems to let you fetch multiple fields if you name your hashes nicely:

redis> hset hash:1 name fish
(integer) 1
redis> hset hash:2 name donkey
(integer) 1
redis> hset hash:3 name horse
(integer) 1
redis> hset hash:1 type fish
(integer) 1
redis> hset hash:2 type mammal
(integer) 1
redis> hset hash:3 type mammal
(integer) 1
redis> sadd animals 1
(integer) 1
redis> sadd animals 2
(integer) 1
redis> sadd animals 3
(integer) 1
redis> sort animals get # get hash:*->name get hash:*->type
1. "1"
2. "fish"
3. "fish"
4. "2"
5. "donkey"
6. "mammal"
7. "3"
8. "horse"
9. "mammal"
