Flavors

A flavors is a reusable collection of plugins with initialized dependencies.

Most importatnt CN-Infra flavors:

• local flavor - a minimal set of plugins. It just initializes logging & statuchek. It is useful for embedding agent plugins to different projects that use their own infrasturcure.
• RPC flavor - a collection of plugins that exposes RPCs. It also register management API for:
  • status check (RPCs probed from systems such as K8s)
  • logging (for changing log level at runtime remotely)
• etcd + Kafka flavor - is combination of Kafka & etcd flavor (reused in many examples)
• all connectors flavor - is combination of all following flavors with local and RPC flavor.

There are following individual connector flavors:

• Cassandra flavor - adds Cassadnra client plugin related instances to the local flavor
• etcd flavor - adds etcd client plugin related instances to the local flavor the local flavor
• Redis flavor - adds Redis client plugin related instances to the local flavor
• Kafka flavor - adds Kafka client plugin related instances to the local flavor

The following diagram shows:

• plugins that are part of the flavor
• initialized (injected) statuscheck dependency inside etcd client plugin and Kafka client plugin
• etcd + Kafka flavor extends local flavor

Overview

Package flavors contains predefined cn-infra flavors. A flavor is a re-usable collection of plugins with initialized dependencies. It is typically used as a starting point for developing a cn-infra based app. A flavor contains plugins required by the app. App developers can also define their own flavors or extend one of the predefined flavors.
