Improving Infinispan's Scalability: A new approach to group communication

Red Hat Developer Program

Infinispan is a distributed in memory key/value store that aims to be highly available and scalable. Its ability to scale is tightly linked to the underlying order protocol, aka atomic broadcast, used for enforcing serializability. In this talk I will explore the scaling limits of Infinispan's existing protocol and then propose an alternative approach to designing broadcast systems, that decouples ordering and broadcast. This talk contrasts our approach with Infinispan's, exploring the design features of our new approach and how they will improve Infinispan's scalability. This talk was be given by Ryan Emerson at the Newcastle JBoss User Group.

While OpenShift natively supports a variety of relational databases (including Postgres and MySQL) as Docker based deployments within the platform, connecting to an existing enterprise database infrastructure is preferred in many large organizations for a variety of reasons including: Inherent confidence in traditional databases due to in house experience around...
