Hi team!
Which client do you recommend for Elasticsearch for spring boot reactive app?
The documentation says 7.15 high level rest client is deprecated in favour of Java API. 7.16 Java API documentation mentions that it is still in beta phase and changes might be expected.
We want to use REST client over transportClient. Can someone please suggest?

Welcome!
For now, I'd still use [Java High Level REST Client | Java REST Client [7.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high.html).
It's marked as deprecated just to inform the community that a new client is in the making.

Thanks David!
Do you forsee any issue in future related to migrating to new client or compatibility with newer elastic versions?

There will be some work to do but that should not be a hard thing to do.
