[英]Nest Update By Id That Is Auto Generated By ElasticDb
I used Nest 6.X framework to manage ElasticSearch with c# At there I shared the result of nest query. 我使用Nest 6.X框架通过c#管理ElasticSearch,在那儿我共享了嵌套查询的结果。
The c# code like this 像这样的C#代码
_elasticSearchDb.Update(DocumentPath<myElasticType>.Id("Cq2jmGgB5bes6sABU8NP"), u => u.DocAsUpsert(true).Doc(myObject));
I want to update a document in an index by documentId that is generated by Elasticsearch as automaticly. 我想通过Elasticsearch自动生成的documentId更新索引中的文档。
At this point, I don't have any problem. 在这一点上,我没有任何问题。
Now think that I have 1 replica and 5 shard on elasticdb. 现在以为我在elasticdb上有1个副本和5个分片。
I have a few doubt when I want to execute this update progress. 当我要执行此更新进度时,我有一些疑问。 For example per day I send request to elasticsearch in different time as total 5000 request at the end of the day.
例如,每天我在不同的时间向弹性搜索发送请求,一天结束时总共发送5000个请求。
At this point, Can I have any performance problem on elastic db? 在这一点上,我可以在弹性数据库上有任何性能问题吗?
Here is the Elaastic Raw Query Request and response that genarated by Nest 这是Nest生成的Elaastic原始查询请求和响应
Note: myElasticIndex and myElasticType terms used as dummny
注意:myElasticIndex和myElasticType术语用作傻瓜

If you have the documents that you wish to upsert, and their ids, you can send them in batches with the Bulk API 如果您有想要更新的文档及其ID,则可以使用Bulk API批量发送它们
var client = new ElasticClient();
var updates = new Dictionary<string, object>
{
{ "id1", new { foo = "bar" } },
{ "id2", new { foo = "baz" } }
};
var bulkResponse = client.Bulk(b =>
{
b.Index("my_index").Type("my_type");
foreach(var update in updates)
{
b.Update<object>(u => u
.Id(update.Key)
.DocAsUpsert()
.Doc(update.Value)
);
}
return b;
});
The TValue
generic parameter of updates can be your POCO type. 更新的
TValue
通用参数可以是您的POCO类型。 This sends the following request 这发送以下请求
POST http://localhost:9200/my_index/my_type/_bulk
{"update":{"_id":"id1"}}
{"doc_as_upsert":true,"doc":{"foo":"bar"}}
{"update":{"_id":"id2"}}
{"doc_as_upsert":true,"doc":{"foo":"baz"}}
