I'm faced with a situation where I need to build an index of about 500,000 records. I'm using the official php client and wondering what should be the right way to do the update. The only solution I can think of is to have a foreach loop and call `$response = $client->index($params);` in it. But is that the right way to go about it or there's something I'm missing out on? Would really appreciate your responses. Thanks! ---

You should use the [Bulk API](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-bulk.html) for this. ---
