[GitHub] [incubator-doris] caoliang-web opened a new pull request #6490: Flink demo
caoliang-web opened a new pull request #6490:
URL: https://github.com/apache/incubator-doris/pull/6490
Flink Demo example:
1.Flink consumes Kafka data and uses Stream load to store data (dorisSink method)
2.Flink reads the file into the library (hdfs file, the format can be text or other), and uses stream load to import
3.Use flink connector to read doris data to build DataStream for sum analysis
