> When trying to use the redis layer for ignite, noticed that the data returned by the mget command is inconsistent. Hence the mget command is broken. To demostrate here is an example
> {code}
> 127.0.0.1:11211> set a 1
> OK
> 127.0.0.1:11211> set b 2
> OK
> 127.0.0.1:11211> set c 3
> OK
> (0.98s)
> 127.0.0.1:11211> mget a b c 
> 1) "1"
> 2) "2"
> 3) "3"
> 127.0.0.1:11211> mget c b a
> 1) "1"
> 2) "2"
> 3) "3"
> 127.0.0.1:11211> mget a c b
> 1) "1"
> 2) "2"
> 3) "3"
> {code}
> If you notice, the order of the values returned does not match the order of the values returned.
> In order to demonstrate the expected behaviour, will run the same commands against a real redis instance and paste the output below.
> {code}
> 127.0.0.1:6379> set a 1 
> OK
> 127.0.0.1:6379> set b 2 
> OK
> 127.0.0.1:6379> set c 3
> OK
> 127.0.0.1:6379> mget a b c 
> 1) "1"
> 2) "2"
> 3) "3"
> 127.0.0.1:6379> mget c b a
> 1) "3"
> 2) "2"
> 3) "1"
> 127.0.0.1:6379> mget a c b
> 1) "1"
> 2) "3"
> 3) "2"
> {code}
> This is not only happening on the redis-cli, it is also happening when using redis client libraries.
