**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser): 2.9

**Describe the issue** :  
[Java client - OpenSearch Documentation](https://opensearch.org/docs/latest/clients/java/) says…

> The OpenSearch Java client allows you to interact with your OpenSearch clusters through Java methods and data structures rather than HTTP methods and raw JSON.

So is there another (low-level) client which would allow me to interact with raw JSON requests and responses (and help in improving latency by avoiding serialisation and deserialisation)?

**Configuration** : N/A

**Relevant Logs or Screenshots** : N/A

You could use RestClient [1], however it is deprecated and is not recommended for use. You mught be rather interested in [2], thank you

Thanks @reta

But as per [Java high-level REST client - OpenSearch Documentation](https://opensearch.org/docs/latest/clients/java-rest-high-level/), [OpenSearch/client/rest-high-level/src/main/java/org/opensearch/client/RestHighLevelClient.java at main · opensearch-project/OpenSearch · GitHub](https://github.com/opensearch-project/OpenSearch/blob/main/client/rest-high-level/src/main/java/org/opensearch/client/RestHighLevelClient.java) is deprecated, not [1].

Is [2] going to be integrated anytime soon?

We are working on that as we speak, thank you
