Hi all,

At Harvard DCE we've been developing a few strategies for automated horizontal scaling of workers. Some involve analysis of AWS CloudWatch metrics and others look at data from Matterhorn itself, e.g. queued jobs. All of them, to a greater or lesser degree, are hindered by the behavior of the job dispatching mechanisms. I'll give a quick example of a typical scenario and why it causes problems for both types of strategies.

Say we have a cluster that has 10 workers at it's disposal but only 1 currently online. A burst of producer activity creates a bunch of new workflows and quickly there are a dozen media inspection and compose jobs generated. What we would expect is that the `max_jobs: n` setting on the worker host would prevent more than n of those jobs from being assigned to the single worker, the rest being put into some sort of queued state. What actually happens is that the 1 worker happily accepts all of them because the dispatching logic in `matterhorn-serviceregistry/.../ServiceRegistryJpaIm

Part-time Software Developer

Harvard Division of Continuing Education (DCE)

Join us as we design and develop the tools and systems that power DCE's teaching and learning environments!

DCE is interested in hiring Less Than Half-Time (LHT) software developers. The DCE Software & Systems Development Group is responsible for creating and maintaining the services used by faculty, producers, instructional design staff, and thousands of DCE students around the world. Projects are varied and range from front-end, JavaScript-powered UI elements, to Canvas LTI integrations, Slack bots, Python and R analytics work, DevOps, AWS infrastructure (including "serverless" apps), and a back-end, distributed, Java application.

Almost all of our development relies on Open Source libraries, and much of our work is released into, or contributed back to, Open Source projects, such as the Opencast Lecture Capture System (https://opencast.org/) and the Paella video player (https://paellaplayer.upv.es/). Feel free to peru
