-# ShardingScaling - ShardingSphere Scaling Out Component
-
-## Overview
-
-The following figure may clearly express this component's role:
-
-
-
-Supplementary instruction about the figure:
-
-1. Support to migrate tables in sharding rule configuration only, can't support to migrate specified tables.
-
-2. The process of migration splits into two steps, inventory data migration and incremental data synchronization.
-
- - During inventory data migration, ShardingSphere-Scaling use `select *` statement to acquire the data, and use `insert` statement to migrate the data to the target;
-
- - During incremental data migration, ShardingSphere-Scaling use binlog to migrate the data, and mark the binlog position before migration.
-
-3. If the table in the source schema has primary key, ShardingSphere-Scaling can migrate it concurrently using `where predication`.
-
-## Requirement
-
-MySQL: 5.1.15 ~ 5.7.x
-
-ShardingSphere-Proxy: 3.x ~ 5.x
-
-## How to Run
-
-Refer to the [Quick Start](https://shardingsphere.apache.org/document/current/en/quick-start/shardingsphere-scaling-quick-start/)

-# ShardingScaling - ShardingSphere弹性伸缩组件
-
-## 概述
-
-下图可以清晰地表明这个组件的作用：
-
-
-
-关于图片的补充说明：
-
-1. 只支持迁移在分片规则中配置的表，暂不支持迁移指定的表。
-2. 迁移过程分为两步——历史数据迁移和实时数据迁移。
- - 在历史数据迁移过程中，ShardingSphere-Scaling 使用 `select *`语句去获取数据，使用 `insert` 语句将数据迁移到目标库中；
- - 在实时数据迁移过程中，ShardingSphere-Scaling 使用 binlog 来迁移数据，并且在迁移前会标记下 binlog 位置。
-
-3. 如果源 schema 中的表有主键，ShardingSphere-Scaling 就能够使用 `where` 声明的条件，并发地迁移表中的数据。
-
-## 环境准备
-
-MySQL：5.1.15 ~ 5.7.x
-
-ShardingSphere-Proxy：3.x ~ 5.x
-
-## 如何运行
-
-参考[快速入门](https://shardingsphere.apache.org/document/current/cn/quick-start/shardingsphere-scaling-quick-start/)
