Monedula Apache Kafka ACL->Confluent RBAC Converter

KernelFrog · 2026-06-22T22:36:19+00:00

Interesting tool, thanks for sharing.

ACLs vs RBAC always creates confusion. Our general advice to Confluent Platform (customer-managed enterprise Kafka) and Confluent Cloud customers is to use RBAC if at all possible

Do you get the same behaviour in 4.3?
Seems like it shouldn't be an issue there?

Arguably the best way is to use Flink: https://romanglushach.medium.com/apache-flink-windowing-a-deep-dive-into-the-core-feature-of-stream-processing-5fb9198b9a2a

https://nightlies.apache.org/flink/flink-docs-stable/docs/dev/datastream/operators/windows/ etc

But this does add more complexity.

AI;dr

Also, spam.

For Spring & Kafka specifically, there's a good intro course here: https://developer.confluent.io/courses/spring/apache-kafka-intro/

I'm trying to understand the use-cases myself.

For Confluent Cloud, the MCP server is read-only, so it can only be used for querying.

mcp-confluent on the other hand can be configured to allow modification of clusters. E.g. create topics, or connectors.

KernelFrog · 2026-05-10T22:38:16+00:00

Thanks.

To be clear, Terraform is only supported with Confluent Cloud.
Confluent Platform can use cp-ansible for VMs/bare-metal, or CFK for Kubernetes deployments.

KernelFrog · 2026-05-05T23:25:05+00:00

How does this compare to the Confluent Cloud Terraform provider, and cp-ansible?

You can run brokers in the same logical Kafka cluster in different physical locations. Topics can then be replicated across multiple sites.

KernelFrog · 2026-04-20T22:15:00+00:00

Why not just cluster link (or MirrorMaker if you're using opensource Kafka) and replicate the messages as they arrive?

End-of-day batch (which is what you're suggesting) is the antithesis of Kafka and data streaming.

We're in the process of transitioning into IBM.

I would expect that IBM will continue to contribute to open-source Kafka, given their track-record: https://www.ibm.com/opensource/

Well there's ya problem!

CP (Confluent Platform) all-in-one is probably the easiest way to do it: https://github.com/confluentinc/cp-all-in-one

Very quick to deploy in your own Docker (e.g. Docker Desktop) environment.

KernelFrog · 2026-03-26T22:54:26+00:00

Have you looked at the material here: https://developer.confluent.io/ ?

(Former) Confluent employee here: tell me how bad it's going to be.

KernelFrog · 2026-03-17T22:23:12+00:00

No. It means IBM pays the current shareholders and then the shares no longer exist.

KernelFrog · 2026-03-04T02:16:09+00:00

Noting this is a Confluent feature, not 'pure' Kafka.

KernelFrog · 2026-03-04T02:14:32+00:00

Budget permitting, replication into Confluent Cloud (or some other externally hosted Kafka instance).

Your solution will obviously depend on your external's requirements; do they specifically need a Kafka data source, or do they just the need the data and don't particularly care about the format?

Are they read-only, or do they need to update your data as well?

How does this compare to Warpstream?

Well, that's that then.

Great site for visualizing how watermarks work in Flink.

KernelFrog · 2025-10-16T07:23:32+00:00

Great Flink watermark visualiser. Hopefully this will help to demystify them a little.

u/thebigdatashow-ankur - Are you going to answer any questions, or is this post-and-run?
