🎯 Collecting Use Case Demos for Apache SeaTunnel

Dear Apache SeaTunnel community members,

We are initiating a community effort to collect real-world use case demos to enrich our documentation and help more users quickly get started and solve their problems with Apache SeaTunnel! 🚀

Why are these demos important?

Many users encounter unique scenarios while using SeaTunnel. By collecting and maintaining these demos, we can:

• Help newcomers: Showcase the broad range of use cases supported by SeaTunnel.
• Provide quick-start solutions: Offer ready-made templates to reduce troubleshooting time.
• Foster community collaboration: Enable others to build and improve upon these examples.

What can you contribute?

1. Share your specific use case:

• Scenario Description: What problem did you solve?
• SeaTunnel Version: The version you were using.
• Configuration or Code Snippet: Key configuration or scripts.
• Outcome: A brief description of the result.

2. Submit a complete demo:

• Organize your configuration files, sample datasets, and documentation into a complete demo.
• Submit a PR to the demos/ directory in the SeaTunnel repository.

3. Share ideas even without a demo:

• If you don't have a complete demo, feel free to share your ideas here. We will help organize and improve them.

Example:

• Scenario: Batch Single Table Synchronization from MySQL to MySQL
• SeaTunnel Version: 2.3.8
• Configuration:

env {
    job.name = "mysql_to_elasticsearch"
    job.mode = "BATCH"
    parallelism = 6
}

source {
    Jdbc {
        url = "jdbc:mysql://xxx:3306/source_db"
        driver = "com.mysql.cj.jdbc.Driver"
        user = "test_user"
        password = "test_pwd"

        table_list = [
            {
                query = "select * from source_db.t1"
                table_path = "source_db.t1"
            }
        ]
        result_table_name = "my-source-1"
    }
}

sink {
    Jdbc {
        source_table_name = "my-source-1"
        url = "jdbc:mysql://localhost:3306/sink_db"
        driver = "com.mysql.cj.jdbc.Driver"
        user = "test_user"
        password = "test_pwd"

        database = "sink_db"
        table = "${table_name}_copy"
        generate_sink_sql = true
        batch_size = 1000

        schema_save_mode = "RECREATE_SCHEMA"
        data_save_mode = "KEEP_SCHEMA_DROP_DATA"
    }
}
