ES中删除索引的mapping字段时应该考虑的点
2020-11-06 21:45:00 【会开车的架构师】
- 创建新索引
- 新索引创建新mapping
- 原索引导出数据到新索引
- 新索引创建原索引一致的别名
- 删除原索引
针对于第四步：这个就要用到索引别名了，如果你最开始建索引的时候没有考虑设计索引别名，那就杯具了。
你可以把索引的名称设置成name_v1 别名设置为name，然后代码里面访问搜索的时候连接的其实是别名name；
这样当你以后索引结构调整需要重新创建的时候，就可以在新建一个索引name_v2，然后把数据初始化完成之后，把原来索引的别名去掉，把name_v2的别名设置成name，这样代码就不用改动了。
