Problem Statement
What do you consider when choosing a serialization format for cached objects?
Explanation
Balance size, speed, and compatibility. JSON is human-friendly but larger; MessagePack or ProtoBuf are compact and fast. Include versioning to handle schema changes without mass invalidation. Avoid embedding unstable fields like timestamps in cache keys to improve hit rate; keep them in payload if needed.
