Can somebody show me a more elaborate example of using the new Java API BulkRequest? I used to be able to set things like bulk size, bulk actions, concurrent requests,... I already took a look at [elasticsearch-java/RequestTest.java at main · elastic/elasticsearch-java · GitHub](https://github.com/elastic/elasticsearch-java/blob/main/java-client/src/test/java/co/elastic/clients/elasticsearch/end_to_end/RequestTest.java#L209-L247) but there is nothing there that casts some light on the problem.  
One other problem, there seems to be no way to simply get the source (as a string) on the BulkResponseItem, BulkResponseItem.get().source() returns a Map\<String, JsonData). A bit cumbersome since we are using GSON and that means an extra conversion step.

If you meant the BulkProcessor, there is no yet a replacement for this helper class AFAIK. It's in the roadmap though.  
So for now, you need to do it manually.

I have an example here:

Have a look at:

There is a pending PR to make that easier in the future.

Thanks for the question about the source. I'm basically doing the same at this point using GSON. I thought the source string was available though without going through a conversion step.

Weird decision on to remove the high level rest client from version 8 without a fully fleshed out new api.
