23 Jun 2020 Jeff Zhang ()In a previous post, we introduced the basics of Flink on Zeppelin and how to do Streaming ETL. Flink’s core is a streaming dataflow engine that provides data distribution, communication, and fault tolerance for distributed computations over data streams. Flink also builds batch processing on top of the streaming engine, overlaying native iteration support, managed memory, and program optimization. There will be compilation errors in tableEnv.registerFunction： "Found xx.xxx.TableFunc0，required org.apache.flink.table.functions.ScalarFunction"。 I did some testing, only Java users have this problem. The following examples show how to use org.apache.flink.table.api.java.StreamTableEnvironment.These examples are extracted from open source projects.
