> Currently, the connection to the Elasticsearch host is opened in
> {{ElasticsearchSink.open()}}. In case the connection is lost (maybe due to a
> changed DNS entry), the sink fails.
> I propose to catch the Exception for lost connections in the {{invoke()}}
> method and try to re-open the connection for a configurable number of times
> with a certain delay.
