First-time contributors' checklist

What is changed, added or deleted? (Required)

Which TiDB version(s) do your changes apply to? (Required)

Tips for choosing the affected version(s):

  • master (the latest development version)
  • v8.5 (TiDB 8.5 versions)
  • v8.4 (TiDB 8.4 versions)
  • v8.3 (TiDB 8.3 versions)
  • v8.2 (TiDB 8.2 versions)
  • v8.1 (TiDB 8.1 versions)
  • v7.5 (TiDB 7.5 versions)
  • v7.1 (TiDB 7.1 versions)
  • v6.5 (TiDB 6.5 versions)
  • v6.1 (TiDB 6.1 versions)
  • v5.4 (TiDB 5.4 versions)

在该模式下，TiKV 执行速度成为迁移进度的主要瓶颈。你可以通过 **TiKV Details** > **Snapshot** > **Snapshot Speed** 面板判断当前调度速度是否达到 TiKV 限流设置。通过调整 TiKV Snapshot Limit ([`snap-io-max-bytes-per-sec`](/tikv-configuration-file.md#snap-io-max-bytes-per-sec)) 来增加或减少该节点的调度速度。

在当前版本中，将该配置项设置为 `"v2"` 为实验特性，不建议在生产环境中使用。

This feature is experimental between 7.1 and 8.5, and will GA in 8.5

@lhy1024 I recommend:

  1. Changing the base of this PR to release-8.4 or release-7.1. I will cherry-pick this PR to v7.1 and later versions.
  2. Creating a new PR to upadte the master branch for v8.5 changes: removing the experimental note in

    docs-cn/pd-control.md

    Line 457 in 3c0975e

    - `store-limit-version` 用于设置 `store limit` 限制模式，目前提供两种方式：`v1` 和 `v2`。默认值为 `v1`。在 `v1` 模式下，你可以手动修改 `store limit` 以限制单个 TiKV 调度速度。`v2` 模式为实验特性，不建议在生产环境中使用。在 `v2` 模式下，你无需关注 `store limit` 值，PD 将根据 TiKV Snapshot 执行情况动态调整 TiKV 调度速度。详情请参考 [Store Limit v2 原理](/configure-store-limit.md#store-limit-v2-原理)。
