Description

https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/table/connect.html#elasticsearch-connector

For append-only queries, the connector can also operate in append mode for exchanging only INSERT messages with the external system. If no key is defined by the query, a key is automatically generated by Elasticsearch.

I want to know ,why the connector of flink with ES just support sink but  doesn't support source .Which version could add this feature to ?
