Flink Elasticsearch connector 7 with SSL

Question

In my flink job, I am trying to use elasticsearch7 connector. I could not find a way to communicate over SSL when using Elasticsearch7SinkBuilder Am I missing something?

Also there is an deprecated class ElasticsearchSink.Builder where it has RestClientFactory which I can use to setup https connection but since this class is deprecated thus wondering if same is possible with Elasticsearch7SinkBuilder .

Also since there is no connector for elasticsearch 8 yet, Is it possible to use any of the above client with elastic 8?

Note: Earlier it used to be elastic connector compatibility matrix in Flink doc but I could not find it any more in lasted version of doc.

SSL connections to Elasticsearch7 are currently not supported and are tracked under https://issues.apache.org/jira/browse/FLINK-27054

An Elasticsearch8 connector is being tracked under https://issues.apache.org/jira/browse/FLINK-26088 . You can't use the ES7 connector to connect to an ES8 cluster.
