What is Protobuf versioning and why is it important?

Protobuf versioning refers to the practice of managing changes to Protocol Buffers (Protobuf) schemas over time. It's important because it ensures backward and forward compatibility, allowing different versions of services to communicate without breaking.

Can you explain how to implement versioning in Protobuf?

To implement versioning in Protobuf, you can use field numbering and reserved keywords. Always increment field numbers when adding new fields and avoid reusing numbers from removed fields to maintain compatibility.

What are some common pitfalls to avoid with Protobuf versioning?

Common pitfalls include reusing field numbers, not using reserved fields properly, and failing to document changes. These can lead to compatibility issues.

How does Protobuf handle backward compatibility?

Protobuf handles backward compatibility by allowing older clients to ignore unknown fields and by ensuring that removed fields are marked as reserved, preventing their reuse.
