如果要解决以上挑战,需要从 TiDB 数据切分以及调度的原理开始讲起。这里只作简单说明,详情可参阅[谈调度](https://tidb.net/blog/a558961f)。
如果要解决以上挑战,需要从 TiDB 数据切分以及调度的原理开始讲起。这里只作简单说明,详情可参阅[谈调度](https://pingkai.cn/tidbcommunity/blog/a558961f)。

TiDB 以 Region 为单位对数据进行切分,每个 Region 有大小限制(默认 96M)。Region 的切分方式是范围切分。每个 Region 会有多副本,每一组副本,称为一个 Raft Group。每个 Raft Group 中由 Leader 负责执行这块数据的读 & 写(TiDB 支持 [Follower-Read](/follower-read.md))。Leader 会自动地被 PD 组件均匀调度在不同的物理节点上,用以均分读写压力。

### 热点

在使用 TiDB 的过程中,热点是一个典型的现象,它表现为大量的流量都在读写一小块数据。由于连续的数据往往由同一个 TiKV 实例处理,因此热点对应的 TiKV 实例的性能就成为了整个业务的性能瓶颈。常见的热点场景有使用自增主键连续写入相邻数据导致的写入表数据热点、时间索引下写入相邻时间数据导致的写入表索引热点等。
