Migrating Applications Between Cassandra Clusters with No Downtime

Learn how to migrate applications between Apache Cassandra™ clusters with zero downtime in this informative conference talk. Discover an open-source, zero-downtime migration proxy that acts as a stateless, horizontally scalable CQL bridge. Explore use cases for cluster migration, including moving to managed Cassandra versions, splitting or consolidating applications, and upgrading to newer infrastructure or Cassandra versions. Understand how the proxy works by synchronously writing to both origin and target clusters while reading from the selected primary cluster. Gain insights into the low-risk, gated migration process that allows for simple rollback and complete control. Hear about real-world examples of successful production traffic migrations without impacting user experience.
