Hai Zhou commented on FLINK-7573:
---------------------------------
Hi [~mingleizhang], Maybe you need to know first:
TCP protocol corresponds to the transport layer, and HTTP protocol corresponds
to the application layer.
in essence, the two are not comparable. The HTTP protocol is based on the TCP
protocol.
> Introduce Http protocol connector for Elasticsearch2

> Key: FLINK-7573
> URL: https://issues.apache.org/jira/browse/FLINK-7573
> Project: Flink
> Issue Type: Improvement
> Components: ElasticSearch Connector
> Reporter: mingleizhang
>
> Currently, all connectors as far as I have known that merely support the TCP
> transport protocol of Elasticsearch, but some of company's ES cluster just
> relies on the HTTP protocol, and close the TCP port on production
> environment. So, I suggest add a new implemention for creating a HTTP
> protocol by using {{JestClient}}, which is a Java HTTP Rest client for
> ElasticSearch.
