What is backward compatibility in Protocol Buffers?
Backward compatibility in Protocol Buffers means that newer versions of a protocol can read data serialized with older versions.
Why is backward compatibility important?
It's crucial for maintaining data integrity and ensuring that systems can communicate without requiring immediate updates.
Can you give an example of how it works?
Sure! If you add a new field to a message, older clients can still read the message without knowing about the new field.
What happens if I remove a field?
Removing a field can break backward compatibility. Older clients won't recognize the absence and may fail to process the message.
How can I ensure my Protocol Buffers are backward compatible?
You can follow best practices like using optional fields, avoiding field number changes, and maintaining default values.
