 # Enable TidbCluster Auto-scaling
 
-Kubernetes provides [Horizontal Pod Autoscaler](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/), a native API based on CPU utilization. Correspondingly, in TiDB Operator 1.1 and later versions, you can enable the auto-scaling feature in a TiDB cluster based on the features of Kubernetes. This document introduces how to enable and use the auto-scaling feature of `TidbCluster`.
+Kubernetes provides [Horizontal Pod Autoscaler](https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/), a native API based on CPU utilization. Based on Kubernetes, TiDB 4.0 has implemented an elastic scheduling mechanism. Correspondingly, in TiDB Operator 1.1 and later versions, you can enable the auto-scaling feature to enable elastic scheduling. This document introduces how to enable and use the auto-scaling feature of `TidbCluster`.

 # 启用 TidbCluster 弹性伸缩
 
-在 Kubernetes 平台上，有着基于 CPU 利用率进行负载的原生 API: [Horizontal Pod Autoscaler](https://kubernetes.io/zh/docs/tasks/run-application/horizontal-pod-autoscale/)。与之相应的，在 Operator 1.1 版本及以上，TiDB 集群可以凭借 Kubernetes 平台本身的特性来开启弹性调度的能力。本篇文章将会介绍如何开启并使用 TidbCluster 的弹性伸缩能力。
