LinkedIn is the world’s largest online professional network with 645+ million members. After outgrowing Oracle and then Memcached, LinkedIn chose Couchbase over MongoDB™ and Redis to be the caching solution for its source-of-truth (SoT) data store. Thanks to its ease of use and extremely low latency, Couchbase quickly became popular with site reliability engineers across the organization. Today, LinkedIn has a Caching as a Service team that uses Couchbase to support over 50 use cases companywide.

“Couchbase is a highly scalable, distributed data store that plays a critical role in LinkedIn’s caching systems.”

  • Backend systems were crashing because Oracle couldn’t effectively scale reads
  • Memcached had reliability issues and was difficult to manage
  • Needed built-in replication and cluster expansion without sacrificing high performance


  • Couchbase is used for all in-memory storage in the datacenter, powering 10+ million queries per second
  • Tremendous performance at scale, averaging <4ms latency for over 2.5 billion items
  • Ease of use, built-in replication and cluster expansion, and automatic partitioning reduced operations costs
