Description:

As part of the development of the checkpoint-restore-operator for managing container checkpoints, it has been identified that there is a need for enhanced functionality related to garbage collection policies and notification mechanisms. This issue serves to track discussions and development efforts regarding these enhancements.

Proposed solution

1. Granular Garbage Collection Policies:
Currently, the operator's proof of concept (POC) implements a global policy for garbage collection. However, it's been proposed to extend the garbage collection mechanism to support granular policies at multiple levels, including per-namespace, per-pod, and per-container policies. This enhancement would provide users with finer control over how checkpoints are managed, allowing them to define policies tailored to specific namespaces, pods, or containers based on their unique requirements and constraints.

2. Custom Parameters for Garbage Collection Policy Adjustment:
Additionally, there's a consideration for allowing users to include custom parameters to adjust the garbage collection policy. This enhancement would enable users to further customize the garbage collection behavior according to their specific use cases and preferences, providing flexibility and extensibility in managing container checkpoints.

3. Notification Mechanism for Garbage Collection:
Another proposed enhancement is the implementation of a notification mechanism to alert administrators or operators when checkpoints are deleted as part of the garbage collection process. These notifications would include details such as which checkpoints were deleted and the reasons behind their deletion, enhancing visibility and transparency into checkpoint management activities.

This issue will serve as a central point for discussions, planning, and tracking progress related to these enhancements. Contributors are encouraged to share their thoughts, suggestions, and contributions to help shape the implementation of these features in the checkpoint-restore-operator for managing container checkpoints.
