Quick Start With Spark

Step 1: Deployment SeaTunnel And Connectors​

Before starting, make sure you have downloaded and deployed SeaTunnel as described in deployment

Step 2: Deployment And Config Spark​

Please download Spark first(required version >= 2.4.0). For more information you could see Getting Started: standalone

Configure SeaTunnel: Change the setting in config/seatunnel-env.sh, it is base on the path your engine install at deployment. Change SPARK_HOME to the Spark deployment dir.

Step 3: Add Job Config File to define a job​

Edit config/seatunnel.streaming.conf.template, which determines the way and logic of data input, processing, and output after seatunnel is started. The following is an example of the configuration file, which is the same as the example application mentioned above.

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

source {
    FakeSource {
      result_table_name = "fake"
      row.num = 16
      schema = {
        fields {
          name = "string"
          age = "int"
        }
      }
    }
}

sink {
  Console {}
}

More information about config please check config concept

Step 3: Run SeaTunnel Application​

You could start the application by the following commands

spark 2.4.x

cd "apache-seatunnel-incubating-${version}"
./bin/start-seatunnel-spark-2-connector-v2.sh \
--master local[4] \
--deploy-mode client \
--config ./config/seatunnel.streaming.conf.template

spark3.x.x

cd "apache-seatunnel-incubating-${version}"
./bin/start-seatunnel-spark-3-connector-v2.sh \
--master local[4] \
--deploy-mode client \
--config ./config/seatunnel.streaming.conf.template

See The Output: When you run the command, you could see its output in your console. You can think this is a sign that the command ran successfully or not.

The SeaTunnel console will prints some logs as below:

fields : name, age
types : STRING, INT

What's More​

For now, you are already take a quick look about SeaTunnel with Spark, you could see connector to find all source and sink SeaTunnel supported. Or see SeaTunnel With Spark if you want to know more about SeaTunnel Run With Spark.

SeaTunnel have an own engine named Zeta and Zeta is the default engine of SeaTunnel. You can follow Quick Start to configure and run a data synchronization job.
