Confluent Kafka Golang Client VS gqlgen

There are two main libraries that people use to write clients Confluent Kafka and segment io kafka

As my first "real world" (ish) project in Vlang, I'm trying to copy https://github.com/confluentinc/confluent-kafka-go, which is a Go wrapper for Kafka C client library, https://github.com/edenhill/librdkafka

You are right, but in practice that's not what happens. Companies do not rely on open source libraries, the developers working for such companies do.

I can give you a realistic example. If you want to use Kafka and Go, your probably only option is to use https://github.com/confluentinc/confluent-kafka-go. Its LICENSE explicitly says "no warranty". Now, what if I find a bug in the library? Only two realistic solutions from my side:

1. I submit the issue and hope for the maintainers to fix it

2. I dig deeper and try to fix the issue. I submit the PR

None of the above scenarios are guaranteed to have a happy ending. The issue could be ignored, or piled up among thousand of other (maybe higher prio) issues. My solution may not be optimal and could be rejected (or if it's optimal, nobody is taking a look at it, and it could remain open for weeks/months).

> If that is a problem for you, negotiate a different contract up front - with the maintainer or someone else willing to do the work. That probably means paying them.

In the real world that would mean that I go to my manager and asks them to pay money to the maintainers of confluent-kafka-go to fix the issue I found. I don't think my manager would approve that, but let's imagine he does. The guys at confluent-kafka-go may not want money to fix the issue. These guys have probably already jobs that pay them well, and they work on the library at will.

Note: I'm talking about confluent-kafka-go, which I know is behind the Confluent software company. But I could as well be talking about libraries maintained by individuals like https://github.com/edenhill/librdkafka

it can be completely statically linked binaries. example: https://github.com/confluentinc/confluent-kafka-go/blob/db57ef6235/kafka/librdkafka_vendor/README.md

If you find the kafka input slow, try kafka_franz. It might be a bit faster, since it’s based on https://github.com/twmb/franz-go. The kafka one is based on https://github.com/Shopify/sarama. You can also write a custom input based on https://github.com/confluentinc/confluent-kafka-go, but this library relies on CGo, which can be annoying.

Last time I checked Confluent does not have a Schema Registry for Go, only for Java, so instead of that I rely on using the guidelines defined for the serialized data, specifically I've used gPRC+Protobuf for doing this, together with buf to detect breaking changes; buf has their own schema registry perhaps that could be something you could explore as well.

So, in the interests of full transparency - we at Zendesk are actually running a fork of confluent-kafka-go, which I forked to add, amongst other things, context support: https://github.com/confluentinc/confluent-kafka-go/pull/626

This bug actually happened because I mis-merged upstream into our fork and missed an important call to rd_kafka_poll_set_consumer: https://github.com/zendesk/confluent-kafka-go/commit/6e2d889...

Setup Kafka Producer using confluent-kakfka-go

I'd suggest https://github.com/confluentinc/confluent-kafka-go we switched from sarama-cluster with minimal work and it works fine. And we process approx 1.2M messages per hour.

In my company we use this https://github.com/confluentinc/confluent-kafka-go,

GraphQL’s spec, as it turns out, does not specify how servers should handle internal errors at all, leaving it entirely to the choice of the frameworks’ creators. Take for example our GoLang GraphQL framework of choice - gqlgen. It makes no distinction between intentional and unexpected errors: all errors are returned as-is to the client within the error message. Internal errors, which often contain sensitive information like network details and internal URIs, would leak to clients easily if not caught manually by the programmer.

Better look into this one: https://github.com/99designs/gqlgen for GraphQL powered by Go. It's spec first approach and requires the least boilerplate code to write. It also incorporates seamlessly with Apollo Federation.

I left PHP for Go.

- with http://sqlc.dev I don't have to write ORM or model code anymore.

- with http://goa.design I can have well-documented API's that any team can generate a client for in any language. It also generates the HTTP JSON and gRPC servers for me so I can focus on my logic.

- with https://github.com/99designs/gqlgen I can define GraphQL revolvers that play well with sqlc (any RDBMS) or I can use a key-value store.

- speaking of key-value stores, Go allows them to be embedded! Even SQLite now has the https://litestream.io/ project to make it super simple to use a durable, always backed-up SQLite database even in a serverless context.

Go is faster, uses less memory, and has really-well designed stdlib without all the bugs I used to face trying to use the PHP stdlib.

Gqlgen if I need GraphQL

Some of these features are inspired by gqlgen so check it out if you need a Golang GraphQL server implementation.

If you want to use GraphQL: https://github.com/99designs/gqlgen

In addition to the ones you mentioned, I also always use: + sqlc - Compile SQL to type-safe code + gqlgen - generate GraphQL server from schema + oapi-codegen - Go client and server boilerplate from OpenAPI 3 specifications + pester - Go http calls with retries and backoff + backoff - exponential backoff algorithm in Go

I have no experience in Django but in Ent with GraphQL.

Ent is not a full-featured web framework so you need to implement many of features by your own or use other libraries (e.g. http server and session management).

If you are only looking for ORM + GraphQL then I highly recommend trying Entgql, an Ent extension for GraphQL with Gqlgen library [1]. Once you define an ORM schema, it will generate GraphQL Query for Relay server. Still you need to implement GraphQL Mutations by your own but at least it will create Input types for you (both for Create/Update).

gqlgen for GraphQL services. It's well documented and maintained.

For me sqlc work wonders. If you are developing a user facing api and are fine to go with graphql, with gqlgen you can even autobind (search the page for @goModel) the models that sqlc generates from your queries. A glorious match
