Database deployment strategies, such as trunk-based, feature-based, and environment-based deployments, each offer unique benefits and challenges for managing schema changes in Database DevOps. Trunk-based deployment facilitates speed and simplicity by allowing developers to commit changes directly to the main branch, though it requires strong automated testing to mitigate risks. Feature-based deployment isolates changes by allowing separate branches for each feature, offering clear ownership and easier rollbacks, but can lead to merge conflicts and delayed integration. Environment-based deployment ensures safety and compliance by progressing changes through sequential environments, though it may slow down delivery. Harness Database DevOps, integrated with Liquibase OSS, supports all three strategies, providing automation, rollback safeguards, and governance to balance speed, safety, and collaboration in database schema management.
