Thanks for your reply. But broadcast state seems not supported in Flink-1.3 . I found this in Flink-1.3: Broadcasting DataStream → DataStream
Broadcasts elements to every partition. dataStream.broadcast(); But I don’t know how to convert it to list and get it in stream context . 在 2018年6月21日，下午5:20，Fabian Hueske <[email protected]<mailto:[email protected]>> 写道： https://ci.apache.org/projects/flink/flink-docs-release-1.5/dev/stream/state/broadcast_state.html
