Persistent Memory Support for Cassandra

DataStax Accelerate 2019

What does a database look like when we have persistent memory as fast as RAM? In this talk, we'll describe how we built an open source persistent memory toolkit for Java and how we rearchitected Apache Cassandra to take advantage of this. We'll show how this resulted in a 9x speedup, or more than double the speed of unmodified Cassandra on the new hardware, and we'll discuss the remaining steps to incorporate our changes into mainline Cassandra.
