This presentation will recount the story of Macys.com (and Bloomingdales.com)'s selection and migration from legacy RDBMS to NoSQL Cassandra in partnership with DataStax.
We'll start with a mercifully brief backgrounder on our website and our business. Then we will go over the various technologies that we considered, as well as our use case-based performance benchmarks that led to the decision to go with Cassandra.
We'll cover the various schema options that we tried and how we settled on the current one. We'll show you a selection of some of our extensive performance tuning benchmarks.
One thing that differentiates this talk from others on Cassandra is Macy's philosophy of "doing more with less." You will see why we emphasize the performance tuning aspects of iterative development when you see how much processing we can support on relatively small configurations.
And, finally, we will wrap up with our "lessons learned" and a brief look at our future plans.
