--------------------------------------
Our company have developed something for flink-connector-es source，but not very well。Because converting SQL to DSL is not very smooth, there are often some issues. For example, memory overflow, fuzzy queries, slow query lookup, etc

> 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.
