。 - - -# 项目设计 -## 架构设计 - -原来的 `index ddl` 基本流程： -+ 修改表 meta 数据 -+ 修改索引数据 -+ finish - -现在，原来的没有变化，只需要把 `修改索引数据` 这里 修改为 `lightning` 来完成就可以了。 -`修改索引数据` 其实也有如下步骤： -+ 将索引列数据，主键数据 取出来 -+ 将 索引列数据 和 主键数据，构造为 kv 保存到本地。 -+ ddl 完成的时候，将 sst 文件 ingest 到 tikv - -该功能，主要涉及到 `tidb/ddl` / `table/tables` 相关组件 - -## 测试 - -- 功能验证 - - admin check - - 跟 ddl 速度对比 - - 是否正常走索引 -- 完备性验证 - - 正常加索引 - - 读时 加索引 - - 写时 加索引 - -
