redis mget vs pipeline

[Shushant Arora]

Hi

I have multiple keys to fetch from redis , which one is more performant mget or pipeline ?

[Jan-Erik Rediger]

Why not test it?

From a purely speculative point of view I'd say MGET:

* Only one command to be parsed
* One path through the code collecting the values
* List of values in a single answer might safe a tiny bit of bytes.

and if multiple keys are hash keys from different fields , can mget be used ? And if I go for hmgetall can I use multiple hmgetall in one go  without pipeline ?

You can.

The answer can be easily found out by sending the commands to a Redis server. If you really don't want to install a Redis server, you can try at the Redis documentation page which provides a sandbox page where you can try the commands.

Correction: MGET only works for string value commands.
