Deserialization reconstructs structured data from serialized bytes. It lets a receiving service read objects sent over a network or stored for later use, but mismatched models can produce dropped fields, default values, or errors. section 12.2
Use deserialization when investigating evolving service data contracts:
- Compare the producer’s payload or schema with the receiver’s model. section 12.2
- Check whether added fields, renamed enum values, optionality changes, or Java version identifiers alter reconstruction. section 12.2
- Distinguish silent data loss and default values from explicit deserialization errors. section 12.2
message Order {
int64 id = 1;
string customer_id = 2;
repeated string items = 3;
optional string notes = 4;
}
A small Protobuf schema shows the fields and optionality that generated classes use during serialization and deserialization. section 12.2
