Sitar-agent: Building a Reliable Dynamic Configuration Sidecar for Large-Scale Environments

Airbnb's dynamic configuration system, Sitar, undergoes multiple configuration changes every minute. The key challenge is delivering these changes to thousands of service instances quickly and reliably without redeployment.

To solve this, Airbnb built Sitar-agent, leveraging the Kubernetes Sidecar pattern. Sitar-agent is responsible for reliably deploying and managing Dynamic Configuration at scale.
