----------------------------------
for option1:
*original* add this method to ApiCallBridge :
SearchResponse search(C client, SearchRequest searchRequest) throws
IOException;
*now* modified to:
// extract SearchResponse and tranform scroll and SearchHit[] to
Tuple2<String, String[]> in every es connector
Tuple2<String, String[]>search(C client, SearchRequest searchRequest)
throws IOException;
> Support source mode of elasticsearch connector

> Project: Flink

> Priority: Major
>
> [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|https://ci.apache.org/projects/flink/flink-docs-release-1.10/dev/table/connect.html#update-modes]
> 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 ?
