Should I always use pipelining when there are more than 1 command in Redis?

I am new to Redis, and a little bit confused when I should use pipelining or should I use it all the time when there are more than 1 command to be sent?

For example, if I want to send 10 SET commands to Redis server at a time, should I simply run the 10 commands one by one or should I pipeline them?

Are there any disadvantage to pipeline 10 SET commands instead of sending them one by one?

Pipeline is used to reduce RTT, so that you can improve the performance, when you need to send many commands to Redis.

It depends. You should discuss it case by case.

if I want to send 10 SET commands to redis server at a time, should I simply run the 10 commands one by one or should I pipeline them?

Pipline these commands will be much faster than sending 10 commands. However, in this particular case, the best choice is using the MSET command.

Are there any disadvantage to pipeline 10 SET commands instead of sending them one by one?

With pipeline, Redis needs to consume more memory to hold the result of all these piped commands before sending them to client. So if you pipe too many commands, that's might be a problem.
