It is not clear as to whether connection pool is available for Elastic REST client - **synchronous** call or not ?
1. If yes, please provide sample configuration class.
2. If not,
2.1 please explain why it is not provided for synchronous calls ?
2.2 please provide sample config class for asynchronous call

Hi,
have you seen our REST client docs? You can find them here: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/index.html) . There are quite some examples in there that should help.
As for your question, I do not understand what you mean by connection pool, could you clarify what you are looking for please?
Cheers
Luca
