Write

Write Components in Ascend are used to export processed data to external systems or storage solutions. They mark the endpoint of a data pipeline. After data is ingested, transformed, and enriched within Ascend, Write Components send it to its final destination. These destinations can include databases, data warehouses, or cloud storage services.

Key Features of Write Components

1. Flexibility in Data Export: Write Components allow you to push data to various external systems, providing flexibility in how and where data is stored or used.
2. Support for Multiple Destination Types: Ascend can export data to many destinations, including SQL databases, NoSQL databases, and cloud storage services like AWS S3 or Google Cloud Storage.
3. Configurability: Write Components are highly configurable, enabling you to specify how data is exported, including its format, batching, and timing.

How Write Components Work

Write Components connect to target destinations using configured Connections. After data is processed within Ascend—through Read Components, Transforms, you can also deliver it to external systems outside of your Data Plane via Write Components. These components prepare the data in the format required by the target system and handle the data transfer process.

Configuring Write Components

info

See the Write Component Reference for more information on the syntax and capabilities of all write component types.

To configure Write Components, you need to specify the destination, the format of the exported data, and any settings required by the target system. This includes credentials for accessing the target system, which Ascend manages securely through its vault system to ensure security and compliance.

Generic Template for Write Connectors

Here is a generic template for configuring Write Connectors in Ascend:

component:
  write:
    connection: <connection-id>  # Required
    <destination-type>:  # Required
      path: <path>  # Required
      format: <format>  # Optional, e.g., csv, parquet
      options:  # Optional, additional options for the write operation
        <option-key>: <option-value>

• connection-id: The file name for the connection to the external system.
• destination-type: The type of the destination, such as database, cloud_storage, etc.
• path: The location or path where the data will be written.
• format: The data format (e.g., csv, parquet). This is optional and can be specified based on the requirements.
• options: Additional options for the write operation, such as settings for data partitioning or compression.

Best Practices for Using Write Components

• Monitoring and Error Handling: Set up robust monitoring and error-handling mechanisms to quickly identify and resolve any issues with data export.
• Security Measures: Securely configure connections used by Write Components, especially when exporting sensitive or regulated data, to prevent unauthorized access.
• Efficiency in Data Export: Optimize the size and frequency of data exports to balance efficiency and performance, particularly when handling large volumes of data or complex transformations.

Conclusion

Write Components are the final step in Ascend's data pipeline, where processed data is exported to its destination for analysis, reporting, or further processing. Understanding the configuration, capabilities, and best practices of Write Components is essential for efficiently managing data exports and ensuring data is available when needed.
