Hi

While bulk insert data into elastic search, I am getting System.OutOfMemoryException.  
Each object is little large, if the number of properties in object is less then data getting inserted.  
(C# coding)  
Is there any solution to avoid this issue.

```
PostData postData = PostData.MultiJson(lstRows);
ElasticsearchResponse<string> indexResponse = objClient.Bulk<StringResponse>(postData);

```

Thanks  
Aneesh
