Can Elasticsearch Java client be updated in run-time?

I am working with an Elasticsearch RestHighLevelClient bean initialized by Spring when my app starts. Now I want to give users the ability to change the connection to Elasticsearch in run-time.

I wonder if there is any elegant way to update a connection to Elasticsearch nodes from a Java client (either the Low Level or the High Level). And by elegant I mean without having to reopen the client for every operation, nor with a flag to inform there was an update.

You can define several ES client beans in your Spring config and qualify (e.g. @Qualifier("one")) them. Then at runtime you can lookup manually the best client by using ApplicationContext#getBean() methods

I don't think that Elasticsearch would have such a possibility.

The solution you are looking for could be Connection Pool. As you mentioned you want to avoid reopening connection for every operation, Connection Pool allows you keeping a few open connections. This is a common pattern for managing many database connections.
