遇到一个问题,我的 elasticsearch 版本是 7.6.1 ,使用的系统是 Debian 9 。我们在线上运行 elasticsearch 时,发现使用 update_by_query 接口发现有时并没有更新,但单个请求又是成功的。什么情况下会显示更新成功,但并没有发生更新呢?请问这个是什么问题,困扰很久了。
经过调试发现一些问题,就是由于我们的更新请求比较多,似乎 elasticsearch 不更新了。
POST /messages/_update_by_query?conflicts=proceed
{
"query": {
"term":{
"roomId":"5d944ee17e78d618bec1a39b"
}
},
"script":{"source":"ctx._source.status = 2"}
}
返回值一开始是
{
"took": 69,
"timed_out": false,
"total": 388,
"updated": 388,
"deleted": 0,
"batches": 1,
"version_conflicts": 0,
"noops": 0,
"retries": {
"bulk": 0,
"search": 0
},
"throttled_millis": 0,
"requests_per_second": -1,
"throttled_until_millis": 0,
"failures": []
}
变成
{
"took": 22,
"timed_out": false,
"total": 388,
"updated": 0,
"deleted": 0,
"batches": 1,
"version_conflicts": 388,
"noops": 0,
"retries": {
"bulk": 0,
"search": 0
},
"throttled_millis": 0,
"requests_per_second": -1,
"throttled_until_millis": 0,
"failures": []
}
updated 值为 0 。频繁更新下 elasticsearch 会不更新吗?
