为了更直观地查验这个问题，我们看看下面的图表。

结果令人担忧，仅需 16 个 informer 就足以导致测试服务器内存耗尽并崩溃，展示了在这些状况下内存消耗快速增长的方式。

## Kubernetes 1.33 update
Since this feature was started, [Marek Siarkowicz](https://github.com/serathius) integrated a new technology into the
Kubernetes API server: _streaming collection encoding_.
Kubernetes v1.33 introduced two related feature gates, `StreamingCollectionEncodingToJSON` and `StreamingCollectionEncodingToProtobuf`.
These features encode via a stream and avoid allocating all the memory at once.
This functionality is bit-for-bit compatible with existing **list** encodings, produces even greater server-side memory savings, and doesn't require any changes to client code.
In 1.33, the `WatchList` feature gate is disabled by default.

## Kubernetes 1.33 更新 {#kubernetes-1.33-update}
自该功能启动以来，[Marek Siarkowicz](https://github.com/serathius) 在 Kubernetes API
服务器中加入了一项新技术：**流式集合编码**。在 Kubernetes v1.33 中，引入了两个相关的特性门控：
`StreamingCollectionEncodingToJSON` 和 `StreamingCollectionEncodingToProtobuf`。它们通过流的方式进行编码，
避免一次性分配所有内存。该功能与现有的 **list** 编码实现了比特级完全兼容，不仅能更显著地节省服务器端内存，
而且无需修改任何客户端代码。在 1.33 版本中，`WatchList` 特性门控默认是禁用的。
