What is the difference between proto2 and proto3?

Proto3 is the latest version of Protocol Buffers and includes the following changes from proto2: Field presence, also known as hasField , is removed by default for primitive fields. An unset primitive field has a language-defined default value.

Why is composition over inheritance?

To favor composition over inheritance is a design principle that gives the design higher flexibility. It is more natural to build business-domain classes out of various components than trying to find commonality between them and creating a family tree.

Is Protobuf dead?

Protocol Buffers is a very mature framework, having been first introduced nearly 15 years ago at Google. It’s certainly not dead: Nearly every service inside Google uses it.

What is the difference between gRPC and rest?

Rules. REST is a set of guidelines for designing web APIs without enforcing anything. On the other hand, gRPC enforces rules by defining a . proto file that must be adhered to by both client and server for data exchange.

Is Protobuf 3 backwards compatible?

One of selling points of Protobuf was backward compatibility, i.e. developers can evolve format, and older clients can still use it. Now with new Protobuf version called proto3, the IDL language itself is not compatible as such things as options , required where dropped, new syntax for enuns, no extention.

What is gRPC client?

gRPC is a modern open source high performance Remote Procedure Call (RPC) framework that can run in any environment. It can efficiently connect services in and across data centers with pluggable support for load balancing, tracing, health checking and authentication.

Is the base class properties included in Base class properties is not included when serializing derived class My apologies but I did not really understand the answers. I am looking for a faster more compact binary serializer and ProtoBuf looks like it might be the answer.

Can you use inheritance in a protocol buffer?

When do you not need inheritance in Java?

3 There is no need to add inheritance, it only serves to bring data-sets from one side to another side. If the one side or the other side want to do calculations that are build inheritance constructs]

Is it good to favor composition over inheritance in gRPC?

GRPC is not doing “favor composition over inheritance” pattern, it’s applying “remove inheritance” pattern. 😀 There are cases when inheritance is more suitable. Just because it’s a good practice to ” favor somehing “, it doesn’t mean it should be removed completely (or not implemented at all).
