问题描述
我正在使用AWS提供的Elastic Search。
I'm using AWS-provided Elastic Search.
我在网站上以及每次注册时都有一个注册页面；为新用户创建了一个新索引（供他的工作组稍后使用），这意味着索引数量在不断增长（现在已达到4〜5k左右）。
I have a signup page on my website, and on each signup; a new index for the new user gets created (to be used later by his work-group), which means that the number of indexes is continuously growing, (now it reached around 4~5k).
我的问题是：索引数量是否有性能限制？在每个用户中动态地创建新索引是否安全（在性能方面）？
My question is: is there a performance limit on the number of indexes? is it safe (performance-wise) to keep creating new indexes dynamically with each new user?
推荐答案
如果我没记错的话，唯一的限制是服务器的磁盘空间，但是如果索引增长太快，则应考虑增加副本服务器。我建议阅读以下页面：
If I'm not mistaken, the only limit is the disk space of your server, but if your index is growing too fast you should think about having more replica servers. I recomend reading this page: Indexing Performance Tips
