Hey Team, I am upgrading from transport client to high level rest client and there are some client level settings I could not find in high level rest client. I was able to upgrade almost all the code but was not able to find some methods used for client initialization. `client.transport.sniff , client.transport.ping_timeout , client.transport.nodes_sampler_interval` I found sniffer in low level client ,is that same as `client.transport.sniff` ? I also found `connect.timeout` and `socket.timeout` in hlrc, are those similar to `client.transport.ping_timeout`? then what about `client.transport.nodes_sampler_interval`? Can anyone help me in this. ---

First of all, the high level rest client is deprecated. So you should directly go to the [Java Client](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/index.html). Then, don't think about it as a 1:1 migration. It's useless to copy/past old deprecated settings to the new way. So for the Low Level client, just look at [Java Low Level REST Client | Elasticsearch Java API Client [8.6] | Elastic](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/java-rest-low.html). There's is barely no specific settings that you must set... If you want to sniff the cluster, that's totally optional, you can use [the sniffer](https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/sniffer.html). I'm not using myself a sniffer as I prefer to control myself the list of the nodes I'm going to connect to. ---

Yes, I was thinking of upgrading to the java api client but I found the documentation a bit incomplete so for the meantime I did the HLRC and will gradually upgrade to the Java Api client. So as per the answer in my new code it is basically not needed to copy paste the old deprecated settings. So I can consider that if in the hlrc initialization if the old settings are not mentioned it is no longer needed? ---

You should use the new client IMO. ---
