sarama VS franz-go

Note: Since there are multiple Go clients for Kafka (including Sarama), please make sure to consult their client documentation to confirm whether they support IAM authentication.

You might want to gradually replace that one with https://github.com/twmb/franz-go because Shopify is looking to find a new owner for Sarama and, until or if they do, it seems to be falling behind with maintenance: https://github.com/Shopify/sarama/issues/2461 For example, they still haven’t addressed this breaking change https://github.com/Shopify/sarama/issues/2358. franz-go has worked well so far in Benthos https://github.com/benthosdev/benthos/tree/main/internal/impl/kafka and it will likely end up as the only implementation once the Sarama-based one will be deprecated

I've used mainly sarama wrapped with a bit of bespoke helper libraries. Never really looked into others, just grabbed one that was actively maintained and went for it.

Well, as someone who reviews a lot of code, I don't like seeing 100s of little files when a handful of logically grouped files would do. For example, this popular go project: https://github.com/Shopify/sarama is currently 256 small .go files, largely following a one class/file rule.

The first example is something we ran into while working on a project. Up until recently, the sarama library (Go library for Apache Kafka) contained the following piece of code (at sarama/version.go):

Im using the go sarama library to connect to the cluster, using this basic example.

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.

There are a few factors that are stopping me from using kafka-go over Shopify's sarama.

Thankfully, Kafka and OpenSearch provide client libraries for a variety of programming languages which make it possible to write your own integration layer. This is exactly what's covered in this blog! We will make use of a custom Go application to ingest data using Go clients for Kafka and OpenSearch.

Can you post the code for that? Franz-go itself publishes benchmark samples for all clients here, so easy to run on your own machine and also review/adapt settings as needed: https://github.com/twmb/franz-go/tree/master/examples/bench

The MSK producer and consumer app use the franz-go library (it also supports MSK IAM authentication).

How to use the franz-go Go Kafka client to connect to MSK Serverless using IAM authentication.

Franz is a fairly obvious name for a Kafka related tool/library so hopefully it won't get confused with https://github.com/twmb/franz-go

github.com/twmb/franz-go -> also early days but this is looking like a fantastic option for a kafka client library if you fancy being an early adopter. I've done the rounds on many kafka client libraries and they always seem to be a harsh compromise in some form or another, but I feel good about this one

Redpanda isn’t implemented in Go, but I second its use over the Apache server. Plenty of clients out there in pure go. https://github.com/twmb/franz-go is a personal favorite
