At Instagram, our mission is to capture and share the world's moments. Our app is used by over 400M people monthly; this creates a lot of challenging data needs. We use Cassandra heavily, as a general key-value storage. In this presentation, I will talk about how we use Cassandra to serve our critical use cases; the improvements/patches we made to make sure Cassandra can meet our low latency, high scalability requirements; and some pain points we have.
