DataStax is now offering Luna for Apache Cassandra® (C*) 4.01, providing enterprise-grade support for open source software users and enterprises. The C* community has made significant improvements in the upcoming 4.0 release, including increased throughput, reduced latency, and easier monitoring. Luna is a subscription service offering support from experts who contributed to Cassandra code. It comes in three tiers: Essentials, Professional, and Enterprise, with no node limits and access to the Luna portal for interaction with C* support team. Starting today, C* 4.0 will be supported by Luna, and future plans include extending support to cover running C* 4.0 in Kubernetes with K8ssandra.
