How to Create a Socket Data Synchronization Jobs​

  • Configuring the SeaTunnel config file

The following example demonstrates how to create a data synchronization job that reads data from Socket and prints it on the local client:

# Set the basic configuration of the task to be performed
env {
  parallelism = 1
  job.mode = "BATCH"
}

# Create a source to connect to socket
source {
    Socket {
        host = "localhost"
        port = 9999
    }
}

# Console printing of the read socket data
sink {
  Console {
    parallelism = 1
  }
}
  • Start a port listening
nc -l 9999

  • Start a SeaTunnel task

  • Socket Source send test data

~ nc -l 9999
test
hello
flink
spark
  • Console Sink print data
[test]
[hello]
[flink]
