Flash Memory technology, deployed as server-side PCIe or solid state disks (SSDs), is emerging as a critical tool for performance and efficiency in data centers of all scales. This presentation will discuss how the use of Flash impacts Cassandra deployments in terms of configuration, DRAM requirements and performance expectations. Ideas on leveraging C*'s cutting-edge data-center awareness to blend flash and disk storage nodes for cost and workload efficiency will also be shared. Flash media itself will be examined from a physical perspective to understand endurance issues. Data on write amplification under bulk-load and operational workload conditions will be presented to explain the impact to Flash of C*'s Log Structured Merge Tree architecture and the associated compactions. Finally, we will examine strategies to make Cassandra more Flash-aware using both conventional techniques as well as emerging Non-volatile memory (NVM) programming capabilities. Lessons learned from real-world customer deployments will be shared to complete this presentation.
