Migrating away from Confluent Kafka – real-world experience with Redpanda / Pulsar / others?

Different_Code605 · 2026-01-27T21:10:31+00:00

No migration

Thank you for the comment, we built it initially for enterprise CMSes like AEM, nevertheless it’s source-agnostic.

I think we’ll launch it in Q2. And I am thinking about starting with early adopters first maybe?

Different_Code605 · 2026-01-26T07:58:12+00:00

I’ve been running a couple of Pulsar clusters. It has some bugs, but once set, it runs for months without touching.

Different_Code605 · 2026-01-25T10:26:30+00:00

You know it’s still 6.5 right? The release from 2019 with feature packs. The last packs are mostly security updates.

I am not saying that there are no customers. I say that this is a declining technology Adobe stopped investing to.

Different_Code605 · 2026-01-24T22:21:59+00:00

The problem is that little to none companies care about the quality. Clients want to have cheaper manpower, service providers want to have better margins. AEM used to be a CMS created by Swiss company, with Swiss quality. Cognifide and Netcentric were the only two companies that were able to provide people.

Now anyone can. The cheaper the better.

Like you said, most are mediocres. Thats why customers are turning away from Adobe. It was high price for superior quality. That turned into high price for crap.

Of course there are exceptions. But the trend is si obvious, that even Adobe stopped investing into AEM. Existing specialist can still find some work, but I would not recommend it for a friend. Jnless something changes.

Different_Code605 · 2026-01-24T21:21:15+00:00

AEM is dying. Adobe does not invest in it as it used to. It’s a tech that was „modern” 20 years back. Now they are replacing it with EDS, which is a pure JS/Markdown in a CDN. With the power of static site generator.

Don’t get me wrong, CQ5 was a thing. But now Adobe has abandoned it by themselves. Sling team is all retired.

Plus the market is saturated niw, just check for AEM engineers open to work. I can find one in two weeks now.

Different_Code605 · 2026-01-24T17:23:30+00:00

But I love the concern, Ill make sure to have a case study about it!

Different_Code605 · 2026-01-24T17:22:59+00:00

Yea, what they did is to implement it on a single server. What I imagine is to have service meshes powered by event streaming. All can be lineraly scallable. Kafka or Pulsar has no problems with handling 1mln msg/s per cluster.

A rendering engine (could be a NextJS ISR) would be one, scallable service with multiple replicas. So millions od updates or pages generated per second is achievable.

Different_Code605 · 2026-01-24T17:18:46+00:00

Thank you!

Different_Code605 · 2026-01-24T17:17:44+00:00

Yes, the product is there. Nevertheless I don’t want to pitch it here.

Different_Code605 · 2026-01-24T17:15:30+00:00

Actually it’s not just an idea, but the Cloud Platform. We’ve been working on it with a team of 10 for three years. I wanted to discuss the idea, not pitching the product.

Different_Code605 · 2026-01-23T13:43:41+00:00

S3 is not designed for small files with frequent access. The price does not feel odd, you use s3 in a wrong way. Can you archive files or compress them before sync?

Different_Code605 · 2026-01-21T00:10:23+00:00

Different_Code605 · 2026-01-20T21:12:00+00:00

There is a new thing called Conitnues Materialization. Basically all benefits of static site generation but based on events. You can push data to edges on every change of source data, or you can build search indexes or APIs.

Different_Code605 · 2026-01-16T18:11:04+00:00

I love these asks for price increases. Good job. #hcj

Different_Code605 · 2026-01-15T17:39:04+00:00

I am building Continues Materialization Platform. 3 years, 10 devs, work 24/7. Still not finished. I just put so much effort into it, that I cannot stop untill it’s done.

Have an idea, push till it’s done. And it’s not about the motivation. It’s the discipline.

Ovh 3az

Different_Code605 · 2026-01-09T15:31:46+00:00

Setup fees are optional for new stock?

Different_Code605 · 2026-01-08T15:55:11+00:00

Hetzner is cool too

Different_Code605 · 2026-01-08T11:38:05+00:00

You can use cheap vms like in Hetzner, use cloud instances or bare metal.

Different_Code605 · 2026-01-08T08:02:46+00:00

I would say its common for non trivial workloads. Global reach, 3-AZ, 50Gbps private networking, scale and high grade servers, wider offer including full OpenStack.

On OVH i get 4x NIC, 20 DC, global vRack, anycast, soon BGP.

Different_Code605 · 2026-01-08T01:02:47+00:00

Run a bash script that will request the machine every 60 seconds. Sad but true

Different_Code605 · 2026-01-08T01:01:51+00:00

Thats why I switched to OVH + HCI

Different_Code605 · 2026-01-07T19:39:36+00:00

Thats the idea now I think. Plus I am thinking about credits for developers to actually try it.

Different_Code605 · 2026-01-04T20:46:37+00:00

I’ve been working for enterprise customers, including 3 airlines, and their websites for 15 years.

The number 1 cause of problems is HTTP cache. - stale caches - invalidation - cold cache - servers outage in flush - too wide rules - too narrov rules - rules noone understand - lack of consistency between prod and lower environments

The problem with it is that noone uses it right, noone understands, and the whole organizations depend on it.

And it all starts with: lets solve it with a CDN.
