    That's not true at all. Case in point In general, this is not a problem that AGC can solve. The language can help (something Java is admittedly particularly bad at) but even so, there'll always be avenues for leaks. That's just the nature of shared things. Interestingly, in the linked grpc case, the leaked memory is only half the problem -- AGC doesn't help at all with the leaked HTTP2 connection.

    I've trialled my new image with an existing project via JLink that's heavy on Netty and gRPC the image works great (with a small tweak to exclude grpc-netty-shaded due to grpc-java#9083).

    When developing an application, the vast majority of code is written by other people. We import that code and make use of it to get whatever we need done. In this case, the developer of an various android applications are using grpc-java.
  • Buf raises $93M to deprecate REST/JSON
    6 projects | news.ycombinator.com | 8 Dec 2021
    `proto_library` for building the `.bin` file from protos works great. Generating stubs/messages for "all" languages does not. Each language does not want to implement gRPC rules, the gRPC team does not want to implement rules for each language. Sort of a deadlock situation. For example:

    - C++: https://github.com/grpc/grpc/blob/master/bazel/cc_grpc_libra...

    - Python: https://github.com/grpc/grpc/blob/master/bazel/python_rules....

    - ObjC: https://github.com/grpc/grpc/blob/master/bazel/objc_grpc_lib...

    - Java: https://github.com/grpc/grpc-java/blob/master/java_grpc_libr...

    - Go (different semantics than all of the other): https://github.com/bazelbuild/rules_go/blob/master/proto/def...

    But there's also no real cohesion within the community. The biggest effort to date has been in https://github.com/stackb/rules_proto which integrates with gazelle.

    tl;dr: Low alignment results in diverging implementations that are complicated to understand for newcomers. Buff's approach is much more appealing as it's a "this is the one way to do the right thing" and having it just work by detecting `proto_library` and doing all of the linting/registry stuff automagically in CI would be fantastic.

  • grpc_bench: open-source, objective gRPC benchmark
    3 projects | /r/grpc | 20 Apr 2021
    Small clarification (to my understanding, I'm not a Java Guru) on why Java got on top - those Java implementations use something called Direct Executor. It's super performant when there's no chance of a blocking operation. But if you are to do anything more than echo service, you might be in trouble. Other implementations probably don't suffer from the same constraint. The related discussion can be found in this PR.

    If you do streaming then the best option would be to use a so called manual flow control. You can find an example here.

    Both JLink (gRPC#3522) and Graal have some issues; I'm especially concerned about the Serial GC in Graal so will be putting that under some stress soon to see if that confirms my suspicions. I'll also be good when some Java 16 JRE Alpine images appear as the JDK is too bloaty.

  • Golang: out-of-box backpressure handling with gRPC, proven by a Grafana dashboard
    4 projects | dev.to | 3 Apr 2024
    gRPC, built on HTTP/2, inherently supports flow control. The server can push updates, but it must also respect flow control signals from the client, ensuring that it doesn't send data faster than what the client can handle.
  • Reverse Engineering Protobuf Definitions from Compiled Binaries
    5 projects | news.ycombinator.com | 9 Mar 2024
    Yes, grpc_cli tool uses essentially the same mechanism except implemented as a grpc service rather than as a stubby service. The basic principle of both is implementing the C++ proto library's DescriptorDatabase interface with cached recursive queries of (usually) the server's compiled in FileDescriptorProtos.

    See also https://github.com/grpc/grpc/blob/master/doc/server-reflecti...

    The primary difference between what grpc does and what stubby does is that grpc uses a stream to ensure that the reflection requests all go to the same server to avoid incompatible version skew and duplicate proto transmissions. With that said, in practice version skew is rarely a problem for grpc_cli style "issue a single RPC" usecases: even if requests do go to two or more different versions of a binary that might have incompatible proto graphs, it is very common for the request and response and RPC to all be in the same proto file so you only need to make one RPC in the first place unless you're using an extension mechanism like proto2 extensions or google.protobuf.Any.

  • gRPC Name Resolution & Load Balancing on Kubernetes: Everything you need to know (and probably a bit more)
    5 projects | dev.to | 6 Feb 2024
    The loadBalancingConfig is what we use in order to decide which policy to go for (round_robin in this case). This JSON representation is based on a protobuf message, then why does the name resolver returns it in the JSON format? The main reason is that loadBalancingConfig is a oneof field inside the proto message and so it can not contain values unknown to the gRPC if used in the proto format. The JSON representation does not have this requirement so we can use a custom loadBalancingConfig .

  • Actual SSH over HTTPS
    9 projects | news.ycombinator.com | 23 Dec 2023
    In general, tunneling through HTTP2 turns out to be a great choice. There is a RPC protocol built on top of HTTP2: gRPC[1].

    This is because HTTP2 is great at exploiting a TCP connection to transmit and receive multiple data structures concurrently - multiplexing.

    There may not be a reason to use HTTP3 however, as QUIC already provides multiplexing.

    I expect that in the future most communications will be over encrypted HTTP2 and QUIC simply because middleware creators can not resist to discriminate.
