Quick Start With SeaTunnel Engine

Step 1: Deployment SeaTunnel And Connectors

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

Step 2: Add Job Config File to define a job

Edit config/v2.batch.config.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"
}
}
}
}

transform {
FieldMapper {
source_table_name = "fake"
result_table_name = "fake1"
field_mapper = {
age = age
name = new_name
}
}
}

sink {
Console {
source_table_name = "fake1"
}
}

More information about config please check config concept

Step 3: Run SeaTunnel Application

You could start the application by the following commands

cd "apache-seatunnel-${version}"
./bin/seatunnel.sh --config ./config/v2.batch.config.template -e local

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:
