Beating round-trip latency with Redis pipelining

16 Apr 2019 - 5 minutes
I worked on a task which involved checking every single value in a Redis instance, and modifying ones which matched a certain format. This script needed to run in a fairly timely fashion, as it would need to be run frequently. Making requests sequentially didn’t cut it, so I learned about pipelining. This simple optimization meant that a script which I originally calculated to take over 50 hours to run ran in under 4 minutes.
