ReactiveElasticsearchClient missing simple count() method

[maxio89]

Is there a way to send a CountRequest without having an entity and repository?
What if I want to count number of documents in some index when having only index name?

The ReactiveElasticsearchClient does not have all the methods that it's imperative counterpart from the Elasticsearch library has. It has basically the methods that were needed to implement the current functionality of Spring Data Elasticsearch.

You can for example use the following code to get the number of entries in an index by using ReactiveElasticsearchOperations:

operations.count(operations.matchAllQuery(), Void.class, IndexCoordinates.of("index-name"));

Or you could add the count method by contributing with a PR.

Hi @sothawo, I noticed the count() method is still not implemented yet, and was wondering if it’s still needed. If so, I’d be happy to contribute.

Feel free to implement this, I think this should be 2 methods then, public Mono<CountResponse> count(CountRequest request) and the variant taking a Function<CountRequest.Builder, ObjectBuilder<CountRequest>> fn as parameter.
