调研方向

首先通过 InformerManager 和 InformerWrapper 跟踪 ManagedInformerEventSource,然后检查 InformerConfiguration 以及现有的 AbstractInformerPool 和 ConfigurationServiceOverrider 入口点。将这些路径与 SharedIndexInformer.removeNamespaceIndex() 进行比较。当一个一等配置选项可以禁用默认的 namespace index,而无需实验性的 pool 子类化,并且覆盖 informer 的启动行为时,即视为完成。

由索引模型根据 Issue 内容生成。

描述

For InformerEventSources, fabric8's default "namespace" index is unused: InformerWrapper.list(namespace) filters the item store directly, and byIndex only serves the JOSDK-qualified custom indexes. The index still costs one entry per object in the watched scope, and when an event source uses a filtering ItemStore to bound its cache, this unused index becomes the dominant retained memory (compounded by the fabric8 cleanup gap reported in fabric8io/kubernetes-client#8103).

fabric8 already exposes SharedIndexInformer.removeIndexer(String), but the SDK offers no path to the informer (it sits behind ManagedInformerEventSource's InformerManager and InformerWrapper, all inaccessible), so today the only way is reflection over three private fields (see the edit below, the experimental informer pool provides a path).

Suggestion: an InformerConfiguration flag (e.g. withoutNamespaceIndex()) applied when the wrapper starts the informer, or an extension point that hands advanced users the SharedIndexInformer for tuning.

Would you be open to a PR for this, and which of the two shapes would you prefer?

EDIT: found out that overriding AbstractInformerPool.start (via ConfigurationServiceOverrider.withInformerPool) allows calling SharedIndexInformer.removeNamespaceIndex() before the informer starts, so reflection is not required after all. The API is marked experimental though, and subclassing the pool for a per-informer concern is indirect, so we think a first-class InformerConfiguration option is still worth it. Happy to include that context in the PR.
