Managing complex data transformations typically involves repeating similar or identical code across multiple transformations. This practice can quickly become cumbersome, error-prone, and difficult to maintain, especially when updates or changes are required. Keboola addresses these challenges effectively with its powerful Shared Code feature. This comprehensive guide provides a deep insight into what shared code is, how it works, and practical examples of its usage.
Shared code in Keboola allows users to define code blocks once and reuse them across multiple transformations. Rather than manually copying and pasting code, shared code creates a centralized, easily editable resource. Any changes to the shared code block can automatically propagate to all transformations referencing it, significantly enhancing consistency and reducing manual errors.
Keboola supports two distinct modes for leveraging shared code: dynamic and static. Understanding these modes helps users pick the right one for their project needs.
In the dynamic mode, transformations reference a shared code block directly. Any change made to the shared code is automatically reflected in all transformations referencing it.
Practical Example: Assume your company uses a shared code block named Sales Metrics across multiple transformations. If your organization needs to update the formula for calculating revenue, you simply update the shared code once. All transformations referencing the Sales Metrics block automatically reflect this updated logic without additional manual intervention.
In static mode, the shared code is copied directly into transformations without maintaining a reference. This mode is suitable when you want specific transformations to remain unchanged, even if the original shared code block is updated.
Practical Example: Suppose you have a shared code block named Customer Segmentation. You may use static mode if certain transformations require a stable segmentation logic that shouldn't be automatically updated when changes are made to the original shared code.
Consider a shared code block named Netflix Titles, which is used to manage various transformations within your project. If the business requires adding a new column, such as Director Name, you can edit the shared code accordingly. Once you save this edit, all transformations referencing the Netflix Titles shared code block instantly receive the new column without manual intervention.
Although shared code simplifies management, caution is necessary when deleting blocks. Removing a shared code block entirely can cause dependent transformations to fail. Errors will appear in job logs indicating missing shared code. To avoid disruptions, carefully verify dependencies before deleting any shared code block.
Keboola's shared code feature simplifies the complexity of managing multiple transformations. It streamlines your data workflows, increases operational efficiency, and reduces human error. With Keboola, your organization can harness the full potential of your data by ensuring consistency and accuracy across all transformations.
