Improving Cache Speed at Scale
Speaker(s): Zohaib Sibte Hassan
In this session I will discuss various techniques we use at DoorDash to improve our tail latencies. With billions of requests coming in it’s really important for us to squeeze every last bit of performance out of Redis. In this session we will discuss some interesting stuff on hot keys, stampede (Thundering Herd), predictive cache expiry, and compression etc.
