What practice is essential for applying version control to data pipelines in Google Cloud?

Implementing CI/CD (Continuous Integration/Continuous Deployment) practices is essential for applying version control to data pipelines in Google Cloud because these practices establish a systematic approach to managing changes in data pipelines. CI/CD allows for automated testing, integration, and deployment of data pipeline updates, ensuring that any changes made to the code or configuration are continuously monitored and can be quickly rolled back if any issues arise.

CI/CD processes facilitate collaboration among teams by enabling multiple contributors to work on the same codebase without conflicts. They also enhance the overall reliability and scalability of data workflows in a production environment. As changes are integrated and deployed, version control systems keep track of revisions, making it easier to maintain, audit, and reproduce data processing steps. This aligns perfectly with best practices in software development, which can be applied to data engineering projects to maintain consistency, quality, and efficiency.

In contrast, while regularly saving snapshots of data (the first choice) can be beneficial for backup and recovery, it does not provide the comprehensive tracking and management of changes that CI/CD practices offer. Creating a static data archive (the third choice) primarily serves as a historical reference without active management of ongoing changes. Lastly, using local versioning on each user's machine (the fourth choice) limits collaboration
