Koord-Queue: Integrating Kube-Queue Into Koordinator

Unifying Kubernetes Scheduling: The Koord-Queue Proposal

Koord-Queue, representing the proposed integration of kube-queue into the Koordinator project, marks a significant step towards streamlining Kubernetes scheduling. This proposal aims to merge the capabilities of kube-queue, a valuable tool for job queuing and fair scheduling, directly into Koordinator. The core idea is to create a cohesive and powerful scheduling solution by integrating kube-queue as a core submodule, named koord-queue, within the Koordinator ecosystem. This strategic move promises numerous benefits, enhancing operational efficiency and providing a more integrated experience for users. The aim of this initiative is to eliminate operational fragmentation. The integration of kube-queue will help to reduce the maintenance burden by streamlining operations and fostering a collaborative environment.

This decision isn't just about code; it's about building a stronger, more user-friendly environment for Kubernetes scheduling. The integration with Koordinator will help to enable deep integration with Koordinator’s resource modeling, priority/preemption, and multi-tenancy features. The outcome will provide users with a cohesive, end-to-end scheduling solution. The transition is designed to be smooth and transparent, ensuring that all existing contributions and user experiences are valued and respected. This integration is about creating a unified scheduling platform that caters to a wide range of workloads, especially those requiring AI, batch processing, and low-latency performance. The goal is to provide a single, comprehensive solution that simplifies scheduling complexity and improves overall system performance.

A Seamless Transition: Preserving History and Recognizing Contributions

The migration to koord-queue is designed to be a respectful and transparent process, ensuring that the contributions of the kube-queue community are fully acknowledged and preserved. All existing code, contributions, and authorship information from kube-queue will be carefully preserved. This means that every commit, every line of code, and every individual who contributed to kube-queue will be recognized within the Koordinator project. The transition also includes the renaming of kube-queue to koord-queue to reflect its new role as a core submodule within Koordinator. This renaming will be accompanied by efforts to maintain backward compatibility, ensuring that existing APIs continue to function as expected wherever possible. Koord-queue will be integrated as a core submodule within the Koordinator repository, residing alongside other key components like scheduler plugins and APIs.

This integration means that koord-queue will be built and released as part of Koordinator, streamlining the development and deployment processes. Recognition of contributors is a key aspect of this transition. All past contributors to kube-queue will be formally acknowledged in Koordinator's documentation and contributor lists. The project also warmly invites kube-queue contributors to join the Koordinator community as members or maintainers. The new koord-queue implementation in Koordinator will include a clear reference to the original kube-queue repository in its documentation and code comments.

Encouraging Community Input and Collaboration

To ensure a successful transition, the Koordinator maintainers are actively seeking input from the kube-queue community. The goal is to foster a collaborative environment where everyone feels heard and valued. As a contributor or user of kube-queue, your feedback is crucial in shaping the future of koord-queue. The community is encouraged to share their thoughts on the proposal, raise any concerns about the migration process, and express their interest in continuing to contribute to koord-queue within Koordinator. The success of this integration depends on the active participation of the community. Therefore, the maintainers are committed to providing clear communication, addressing all concerns, and ensuring a smooth transition.

The initiative is designed to strengthen both projects and better serve the Kubernetes scheduling community. By integrating kube-queue into Koordinator, the aim is to create a more powerful and versatile scheduling platform. The Koordinator team is committed to making this a positive experience for everyone involved. They appreciate all the contributions and are looking forward to this next step together. The migration process is designed to be open and transparent, with ample opportunities for the community to provide feedback. The goal is to create a scheduling solution that meets the needs of a wide range of users and workloads, from AI and batch processing to latency-sensitive applications.
