Building Centralized Caching Infrastructure at Scale

Caching is integral to any large-scale web operation. LinkedIn formed a dedicated caching team in 2017 and since then we have built out automation and infrastructure to support over 7 million queries/second across more than one-hundred clusters.

In this talk, I will be speaking through:

  • Why this team needed to exist
  • What we wanted to improve (e.g. tighter integration with existing deployment infrastructure)
  • How we integrated a third-party product into our deployment system
  • Things we wish we did differently after implementing our initial automation/tooling
  • Implementing seamless upgrades (compare it to how things were in the past)
  • Transitioning from running in root to non-root
  • Tooling we created to provision stores quickly
  • Where we want to take caching at LinkedIn
  • Things to consider about if your team provides a datastore as a service

James Won is a Staff Site Reliability Engineer at LinkedIn, responsible for keeping its caching infrastructure running smoothly and scalable. He not only spends time in the day-to-day operations of maintaining caching infrastructure but is also a huge fan of Python and thus automates as much as he possibly can to reduce human error and make tasks as self-service as possible.
