> flink version: 1.11.1
> elasticsearch connector version: 6.3.1
> My job graph is [kafkaSource--> map–>elasticsearchSink], when I set a larger
> degree of parallelism, stream processing will stop, I know es has an issue
> [47599|https://github.com/elastic/elasticsearch/issues/47599], this is
> unexpectedly the risk of deadlock when using flink-connector-elasticsearch6.
