New Kubernetes Operator for a Distributed Database

Recently KubeCon 2019 was held in San Diego. At DataStax where I work we had a release at KubeCon of our DataStax Enterprise Distributed Database Kubernetes Operator.

I got to catch up with Christopher Bradford about this release of the DSE K8s Operator on the Distributed Data Show. Here’s the podcast of the DDS DSE K8s episode with time points below the links:

The Podcast, “First Look at the DSE Kubernetes Operator with Christopher Bradford | Episode 128 Distributed Data Show”

• Podcast on iTunes
