#### Docker Known Issues

##### 1.9.1

  * Listing containers can be slow at times which will affect kubelet performance.
More information [here](https://github.com/docker/docker/issues/17720)
  * Docker daemon restarts can fail. Docker checkpoints have to deleted between

### etcd moves to version 3.5.0

* **Safer** types.
* Better **performance** and **less energy** consumption.
* Better **extensibility**.
* etc.

...all this while keeping the **same Python API**. In most of the cases, for simple models, you can simply upgrade the Pydantic version and get all the benefits. 🚀

In some cases, for pure data validation and processing, you can get performance improvements of **20x** or more. This means 2,000% or more. 🤯

 * Iterator}. Except as noted, each method has a corresponding {@link Iterable}-based method in the

 * <p><i>Performance notes:</i> Unless otherwise noted, all of the iterators produced in this class
