Is it possible to execute the following request asynchronously on the server side?

```auto
POST test/_update/1
{
  "script" : "ctx._source.new_field = 'value_of_new_field'"
}

```

By "server side", I mean server should write the request to the translog and respond immediately before applying any changes(get doc, execute script, index doc) .

I am using the Java rest client.

I do not think that is possible. Why would you want to do that? What are you hoping to gain?

What I try to achieve is to have high throughput on the client-side without delays.

If you want high throughput you should look at [this part of the docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.13/tune-for-indexing-speed.html). The most important tip for optimising throughput is to use bulk requests as lots of single index or update requests limits performance.
