    The classic answer is protobufs. You can serialize out to binary format.
  • 2022-01-11 gRPC benchmark results
    3 projects | | 12 Jan 2022
    Seems like go is pretty middle of the road. I can only guess as to why but it probably has to do with heavy usage of pointers and reflection which are much slower than other implementations. Gogo/protobuf (RIP) solved this performance with code generation, but the the official go protobuf implementation has essentially eschewed it. I do wonder how the benchmark would look using the new vitess proto library for Go (which has many of the benefits of gogo but with active development and an API built on top of the Google one)

  • A new ProtoBuf generator for Go
    7 projects | | 3 Jun 2021
    Maybe I'm missing something, but my read of [golang/protobuf#364]( was that the re-organization in protobuf-go v2 was allow for optimizations like gogoprotobuf to be developed without requiring a complete fork. I totally understand that the authors of gogoprotobuf do not have the time to re-architect their library to use these hooks, but best I can figure this generator does not use these hooks either. Instead it defines additional member functions, and wrappers that look for those specialized functions and fallback to the generic ones if not found.

    I am thinking about stuff like the [ProtoMethods]([email protected]/reflec...) API.

    I wonder why not? Did the authors of the vtprotobuf extension not want to bite off that much work? Is the new API not sufficient to do what they want (thus failing some of the goals expressed in golang/protobuf#364?

    In this case try approach with line by line generation. Very much like what protoc-gen-go does for Go code:, need to implement this kind of generator yourself.

    The difference to the client-server solution is subtile when it comes to the details in implementation. protoc-gen-go and other plugins in the Protocol Buffers ecosystem use this approach.

  • Intro to gRPC

    There are examples in several languages here: That directory looks a bit scarier than it is because each language typically implements several servers to illustrate different concepts. A single server in that directory is typically about one source file and same with a single client.

    You may already be familiar with the remote procedure call framework gRPC. Given the similarity in naming, you might be inclined to believe that tRPC is somehow related to it, or does the same or a similar thing. However, this is not the case.
  • Let's build a simple asynchronous Web3 client for Ethereum blockchain in python
    2 projects | | 24 Apr 2022
    Ethereum has a very well defined set of methods that can be used to interact with the blockchain from external systems (probably from our current Web 2.0 systems). Ethereum exposes these functionalities over JSON-RPC 2.0 protocol. In brief, JSON-RPC is a light-weight data interchange protocol built on top of application layer protocols like HTTP and Web Sockets. Using JSON-RPC we specify the method we want to invoke and the list of parameters to be passed, the method is then executed by the Ethereum's JSON-RPC server to which we have connected and returns the output as JSON which can be consumed by the caller. When compared to gRPC and other known RPC protocols JSON-RPC is relatively simple and uses plain text JSON which is more readable and easily understandable. We can see the list of methods provided by Ethereum blockchain via JSON-RPC protocol here.

  • When to use GraphQL, gRPC, REST, and Webhooks
    2 projects | | 30 Mar 2022
    When it comes to architecting an application, developers have a wide range of client-server communication protocols to choose from. It’s pretty popular across modern apps to use GraphQL, gRPC, REST, and Webhooks. Depending on the needs of your application, each protocol can offer different benefits.
  • Configuring GRPC keepalive
    1 project | | 28 Mar 2022
    So, a keep-alive operation consists of 4 packets, all four are 68 bytes long; eg. one keep-alive operation is 272 bytes long. There are 86400 seconds in a day, so 86400/15 = 5760 keep-alive operations are done in a day; it means 5760*272 = 1 566 720 bytes ~ 1.5 MB/day! My whole month data usage could be that much, not my daily. As 1 MB/month is around 1 EUR/month/device, 50 MB is 2.65 EUR/month/device. So, I've tried to set the keep-alive options on client side: conn, err := grpc.Dial(*addr, grpc.WithInsecure(), grpc.WithKeepaliveParams(keepalive.ClientParameters{Time: 60 * time.Second, Timeout: 5 * time.Second, PermitWithoutStream: true})) But after 3 minutes the connection is dropped. The keep-alive documentation ( and is contradictory.
