Presenter: Rick Branson, Infrastructure Engineer at Instagram
As Instagram has scaled to over 200 million users, so has our use of Cassandra. We've built new features and rebuilt old on Cassandra, and it's become an extremely mission-critical foundation of our production infrastructure. Rick will deliver a refresh of our use cases and go deep on the technical challenges we faced during our expansion.
