7a8a4c201a Merge pull request #129933 from serathius/deprecate-namespace-index 
Disable StorageNamespaceIndex feature gate when BtreeWatchCache enabled and deprecate it
 2025-02-11 06:29:59 -08:00

b1ad53c533 Disable StorageNamespaceIndex feature gate when BtreeWatchCache is enabled and deprecate it 
Previously, the cache used a map keyed by the full object key,
requiring iteration and filtering by namespace for namespace-scoped requests.
This index allowed for faster responses by avoiding this iteration.

With the introduction of the BtreeWatchCache, this optimization is no longer necessary.
The B-tree structure allows efficient prefix-based searches,
including fetching objects by namespace.
Furthermore, the B-tree returns elements ordered by key, eliminating the need for separate sorting.

Performance improvements with the BtreeWatchCache have been validated through benchmarks matching K8s scalability dimentions (see table below).
These results demonstrate that the B-tree approach provides comparable or better performance than the map with index.
Therefore, the StorageNamespaceIndex feature flag can be safely flipped to false and subsequently deprecated.

8a908e0c0b remove import doc comments 
The "// import <path>" comment has been superseded by Go modules.
We don't have to remove them, but doing so has some advantages:

- They are used inconsistently, which is confusing.
- We can then also remove the (currently broken) hack/update-vanity-imports.sh.
- Last but not least, it would be a first step towards avoiding the k8s.io domain.

This commit was generated with
   sed -i -e 's;^package \(.*\) // import.*;package \1;' $(git grep -l '^package.*// import' | grep -v 'vendor/')

Everything was included, except for
   package labels // import k8s.io/kubernetes/pkg/util/labels
because that package is marked as "read-only".
