Preamble
Redis Pipeline is technique for improving performance by wrapping up
bunch of Redis commands into a single process, without waiting for
the response to each individual command.
Round-Trip Time (RTT)
Redis client-server using TCP connection to established, where the
client send redis command to the server and client waiting
for server to response, that’s how Redis command executed without
Pipeline, it’s still ok if you only execute one command, when
you execute multiple command it’s going to be faster if you
use pipeline.
No Pipeline
Client ask to open connection to server, and execute one redis
commands through one TCP request, and client do the same but with
different redis command, until 3 times and connection closed.
Pipeline
Client ask to open connection to server, and execute several
redis commands through one TCP request, and server executing all
commands that client sent, without response each command status
to client, after server done, it will send response to client
that pipeline already execute those commands.
Benchmark Result
This benchmark data generated by golang benchmark, I use golang as the redis client for prove which one is faster by comparing bulk insert 1024 data, using Non Pipeline & Pipeline.
Non Pipeline
Non Pipeline take more and more time, through data quantity from 1 to 1024, it’s going slower because Non pipeline execute insert command and waiting the response, and executed inside different TCP Request, it’s mean if the data quantity increase it goes slow, because the client perform 1024 TCP Request to server.
Pipeline
Pipeline time execution is almost linear, with pipeline the client perform multiple command that sent through one TCP Request, and server execute all the commands and response to client when all commands already execute, pipeline process 1024 command faster.
Conclusion
It’s all depends on your need, don’t over engineering simple task, if you need to perform multiple commands with faster, you can go with pipelined command, otherwise if you just perform one command you can go with non pipelined command.
