kafka-go VS franz-go

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

Unlike the standard scripts, and many binary clients, it's a native, statically-compiled, binary. It uses segmentio/go-kafka internally, which means CGO can be disabled during compilation.

Scaling up our producers/consumers proved to be more cost-effective than adding more CPU/brokers to the Kafka cluster. To accomplish this, we used the segmentio/kafka-go client library which provides an excellent abstraction for interacting with the cluster and will handle data compression completely transparently.

I want to announce the first release of a kafkagosaur, a new Kafka client. It's built using WebAssembly and binds to the kafka-go library. The first release includes functionality to read and write Kafka messages and SASL support.

Use the Segment Kafka library, not Sarama, it’s much easier to use https://github.com/segmentio/kafka-go

Segment learned quite some time ago that librdkafka-go has problems like these (and doesn’t support Contexts either), so they wrote a pure Go replacement instead. https://github.com/segmentio/kafka-go

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.

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

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).

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

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.

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
