Operating Cassandra in Kubernetes with Temporal

Explore how Datadog operates Cassandra in Kubernetes using Temporal Workflows in this conference talk. Learn about the challenges of running stateful applications like Cassandra on Kubernetes and how Datadog leverages init-containers, entrypoint scripts, and pod-lifecycle hooks for node addition and replacement. Discover how Temporal Workflows automate complex operations, including infrastructure migrations, progressive rollouts, and deployments with enhanced health-checks and guardrails. Gain insights into the features provided by existing tools and the gaps they left unaddressed. Understand the properties of Temporal that make it an attractive solution for orchestrating slow processes involving streaming or compaction. Examine specific use-cases implemented as Temporal Workflows and their impact on Cassandra operations in a Kubernetes environment.
