Explain event schemas and why schema registries matter at scale
This tests schema evolution and data contracts in distributed systems. A good answer defines schemas as contracts, explains that a registry enforces compatibility to block breaks, and lists pain like pipeline failures. Never treat schemas as optional docs.
This tests schema evolution and enforceable data contracts in distributed systems. A strong answer defines an event schema as a typed contract with field names, types, and semantics; explains that a registry or governance tool like Segment Protocols centralizes contracts to enforce compatibility and prevent breaking changes; and details scaling pain like pipeline failures, null-heavy warehouses, and divergent analytics. A red flag is treating schemas as passive documentation instead of enforced contracts.
