调研方向
从 @ControllerConfiguration 注解开始,追踪 Cleaner 实现如何在删除 custom resource 期间触发 finalizer 处理。确认 delete event 在哪里处理,以及如何调用 cleanup。完成的标准是:所提出的配置能够控制 cleaner 是否添加 finalizer,而不改变 cleanup 行为,并且相关行为有测试覆盖。
由索引模型根据 Issue 内容生成。
描述
If Cleaner interface is implemented by a reconciler a finalizer is automatically added to the custom resource, and cleaner is called before it gets removed.
There is however a corner case when it makes sense to do cleanup event finalizer is not used. In case there is an in memory data held for a custom resource, so when a custom resource deleted, related indexed or in memory objects needs to be cleaned up. In this case a finalizer is not needed, since if the operator is down and the delete event is missed it's not a problem, since the cleanup is just for in memory data.
To support this we could add a feature flag to @ControllerConfiguration to don't add finalizer for cleanup: addFinalizerForCleaner.
Note that this is not a priority issue, we should probably implement it only if some requests it. Also having a finalizer in those cases would not be a big issues.
