If you want / have to connect to your Elasticsearch cluster via REST-client, I recommend to use JEST client instead. Failure scenarios and expected exceptions are the same as in the It can be hard to get good upload performance though which is where the Bulk API comes in. When executing a BulkRequest in the following manner, the client waits for the BulkResponse to be returned before continuing with code execution: BulkResponse bulkResponse = client.bulk(request, RequestOptions.DEFAULT); Synchronous calls may throw an IOException in case of either failing to parse the REST response in the high-level REST client . In such situation it is necessary to iterate over all operation results in order If you find any issues regarding the post feel free to reach out to me. In this post, we will see how to bulk insert data using Java High Level Rest Client. We create a BulkProcessor, we read from our data file, we wrap each line up in an IndexRequest as a JSON document and we add that to the BulkProcessor You can find this code in the repository as BulkProcessorUpload.java.
