Dealing with Data in Dynamic Systems

In an ideal scenario, feature development is easy. Just replace the old code with new code, and you’re done. This is, in fact, true for a system in a state of inertia. However, constantly moving pieces of business logic in a dynamic system presents a complicated problem. There are several unanswered questions while deploying huge schema or logic changes: How do you make code and schema changes with zero downtime or service interruption? How do you optimize online migrations of data to allow for fallbacks? Any changes in schema or code in dynamic systems may cause existing users to experience downtime. This talk focuses on strategies to ensure backward compatibility and prevent breaking data integrity.
