PUT <my-index-{now/d}-000001>
PUT %3Cmy-index-%7Bnow%2Fd%7D-000001%3E
{
"aliases": {
"my-alias": {
"is_write_index": true
}
}
}
如果大家对于上面的字符串 "%3Clogs-%7Bnow%2Fd%7D-1%3E" 比较陌生的话，可以参考网站 URL Encode Online | URLEncoder。实际上它就是字符串 "<logs-{now/d}-1>" 的url编码形式。请注意上面的 is_write_index 必须设置为 true
The following request only rolls over the alias if the current write index meets one or more of the following conditions:
- The index was created 7 or more days ago.
- The index contains 1,000 or more documents.
- The index's largest primary shard is 50GB or larger.
