问题描述
我在使用批量API(C#NEST v5.4)插入文档时遇到问题.我有一个文档数组,在数组中有我的ID.
I'm facing a problem inserting document using bulk API (C# NEST v5.4). I've an array of documents and inside of the array I've my ID.
我的代码是:
documents = documents .ToArray();
Client.Bulk(bd =>
bd.IndexMany(documents,
(descriptor, s) => descriptor.Index(indexName)));
如何使用描述符手动插入 _id ?
How can i insert the _id manually using the descriptor?
提前谢谢!
推荐答案
您可以类似于在BulkDescriptor
上设置索引名称的方式设置_id
.鉴于以下POCO
You can set _id
similarly to how you're setting the index name on the BulkDescriptor
. Given the following POCO
public class Message
{
public string Content { get; set; }
}
例如使用递增计数器设置ID
Setting the ids using an incrementing counter for example
var documents = new[] {
new Message { Content = "message 1" },
new Message { Content = "another message" },
new Message { Content = "yet another one" }
};
var indexName = "index-name";
var id = 0;
client.Bulk(bd => bd
.IndexMany(documents, (descriptor, s) => descriptor.Index(indexName).Id(++id)));
产生以下请求
POST http://localhost:9200/_bulk
{"index":{"_index":"index-name","_type":"message","_id":1}}
{"content":"message 1"}
{"index":{"_index":"index-name","_type":"message","_id":2}}
{"content":"another message"}
{"index":{"_index":"index-name","_type":"message","_id":3}}
{"content":"yet another one"}
