Thoughts on using Kafka with Node.js (node-rdkafka)
Let me start by saying, node-rdkafka is a godsend. When we first started using it, the library was the only one fully compatible with the latest version of Kafka and the SSL and SASL features.

Kube-Native Workflows with Argo
Stitching Docker containers together to get stuff done fast!
