This presentation will start with a brief introduction about the fingerprinting engine in Jenkins and its use case. Then we will discuss the motivation behind externalizing these fingerprints. We will discuss the external fingerprint storage API built during the course of the project, and what features it allows the plugin developers to use. Then we will talk about the two reference implementations built by us during the project, backed by Redis and PostgreSQL. We will discuss fingerprint cleanup and migration strategies. A demo will be presented which will show the working of the plugins and their functionality in action. We will conclude the presentation with what potential future areas of improvement can be for this project where the community is more than welcome to contribute.
