Hi, We need to upgrade out Elasticseach from 8.x.x to 9.x.x. The flink project is connecting to ES 8.x.x and we still use the RestHighLevelClient which has still compatibility.
Since we will be upgrading to ES 9.x.x, we are also upgrading our Flink 1.20 to Flink 2.0 and in documentation, the connector is still Elasticsearch7, which might not work. Is there anyway we can connect to ES 9.x.x from Flink 2.0 sink? Any advise is appreciated. Regards,
