Re: [go-nuts] what's the most popular kafka library to use

I'm try all kafka libraries and my list: 1. github.com/twmb/franz-go/kgo - the best, no problems is around 1.5-2 years 2. github.com/segmentio/kafka-go (cool but have some errors 1.5 years ago, so i broke my production cluster with it) -- Vasiliy Tolstov, e-mail: v.tols...@selfip.r

Re: [go-nuts] "go test": common prefix for errors

I'm not sure I completely grasp the use case here in detail, but FWIW, I explored collation of log lines per-test with https://pkg.go.dev/golang.org/x/exp/slog a while ago and ended up with a struct that implements both testing.TB and slog.Handler. The idea was: (1) testing.TB methods that log,

[go-nuts] what's the most popular kafka library to use

Currently I'm interested only in consuming/producing. I'm aware of *confluent-kafka-go *and of *sarama, *and it looks like sarama has more github swag, but other than that I have no idea which one is better/more popular. Is there an obvious choice here? what are people using now days (March 202

Re: [go-nuts] How to encode/decode string to binary in golang

Relating to my previous question, I have been reading but it is still not clear to me what raw binary is, how is it different from text formatted binary (fmt.Sprintf("%b", s1s2Byte))? In my problem above I need to encode s1+s2 to raw binary before sending the result to the server which then decodes

Re: [go-nuts] How to encode/decode string to binary in golang

Do you mean encoding should be rawdata := fmt.Print("%016d%s%s", len(s1), s1,s2) or rawdata := fmt.Printf("%016d%s%s", len(s1), s1,s2) On Monday, March 13, 2023 at 4:36:50 PM UTC+2 Alex Howarth wrote: > You might be looking for strconv.ParseUint() > https://pkg.go.dev/strconv#ParseUint > > h

With contextual logging, do we now have a better pattern easily available? Associate with the context a Logger that goes to T.Log? On Monday, March 13, 2023 at 5:00:51 AM UTC-4 Patrick Ohly wrote: > The underlying problem is that a "go test" only has one output stream: the > text written via `T

Re: [go-nuts] "go test": common prefix for errors

The underlying problem is that a "go test" only has one output stream: the text written via `T.Log`. Additional output on stdout or stderr isn't associated with the test that produced it, which is bad when running tests in parallel or when running without "go test -v". Sean Liao schrieb am Frei
