I'am trying to insert multiple records into my database using Nest. Inserting using IndexMany class does work however I also need to insert objects by json string.
I did look on github, and found some examples how to use the RAWclient. Below a code example I insert my json.
> var twitter = _jsonData;
> var result = client.Raw.BulkPost(
> new { twitter }
> , qs => qs
> //.Replication(ReplicationOptions.Async)
> .Refresh(true) );
some additional info:
jsondata:
tweet tweet1 = new tweet { id = "104", name = "test104", lastname = "test107" }; //ect....
List<tweet> data; //multiple tweet objects are added
string json = Newtonsoft.Json.JsonConvert.SerializeObject(data);
var twitter:
{
"twitter": "[{'name':'test104','lastname':'test107','id':'104'},{'name':'test105','lastname':'test108','id':'105'},{'name':'test106','lastname':'test109','id':'106'}]"
}
result i receive from the database:
{"error":"Unexpected end-of-input: expected close marker for OBJECT (from [Source: [B@10893e4; line: 1, column: 0])\n at [Source: [B@10893e4; line: 2, column: 3]"}
Does anyone know what the issue might be? or what I'am missing in my json/code snipped?
Your json is not correct for elasticsearch bulk operation. See the documentation .
In a bulk request every data object should be preceded by a command because a single bulk request can contain inserts, updates or deletes, not just inserts. So your json should look like
{ "index" : { "_index" : "twitter", "_type" : "tweets" } }\n
{'name':'test104','lastname':'test107','id':'104'}\n
{ "index" : { "_index" : "twitter", "_type" : "tweets" } }\n
{'name':'test105','lastname':'test108','id':'105'}\n
{ "index" : { "_index" : "twitter", "_type" : "tweets" } }\n
{'name':'test106','lastname':'test109','id':'106'}\n
To reduce overhead from repetitive commands you can move some arguments to the request uri. Then the json can be shorter:
{ "index" : { } }\n
{'name':'test104','lastname':'test107','id':'104'}\n
In IRawElasticClient that means moving them to BulkPost arguments.
var result = client.Raw.BulkPost(new { twitter }, "twitter", "tweets");
