Multiple table

example1

env {
  parallelism = 1
  job.mode = "STREAMING"
  checkpoint.interval = 5000
}

source {
  Mysql-CDC {
    base-url = "jdbc:mysql://127.0.0.1:3306/seatunnel"
    username = "root"
    password = "******"
    
    table-names = ["seatunnel.role","seatunnel.user","galileo.Bucket"]
  }
}

transform {
}

sink {
  Http {
    ...
    url = "http://localhost/test/${database_name}_test/${table_name}_test"
  }
}

example2

env {
  parallelism = 1
  job.mode = "BATCH"
}

source {
  Jdbc {
    driver = oracle.jdbc.driver.OracleDriver
    url = "jdbc:oracle:thin:@localhost:1521/XE"
    user = testUser
    password = testPassword

    table_list = [
      {
        table_path = "TESTSCHEMA.TABLE_1"
      },
      {
        table_path = "TESTSCHEMA.TABLE_2"
      }
    ]
  }
}

transform {
}

sink {
  Http {
    ...
    url = "http://localhost/test/${schema_name}_test/${table_name}_test"
  }
}
