At this yearās Kafka Summit Iām planning to continue the tradition of going for a run (or walk) with anyone whoād like to join in. This started back at Kafka Summit San Francisco in 2019 over the Golden Gate Bridge and has continued since then. Whilst Londonās Docklands might not offer quite the same experience itāll be fun nonetheless.
This year Kafka Summit London includes a dedicated track for talks about Apache Flink. This reflects the continued rise of interest and use of Apache Flink in the streaming community, as well as the focus that Confluent (the hosts of Kafka Summit) has on it.
Iām looking forward to being back at Kafka Summit. I will be speaking on Tuesday afternoon, room hosting on Wednesday morning, and hanging out at the Decodable booth in between too.
Hereās a list of all the Flink talks, including the talk, time, and speaker. You find find more details, and the full Kafka Summit agenda, here.
At Decodable we migrated our docs platform onto Antora. I wrote previously about my escapades in getting cross-repository authentication working using Private Access Tokens (PAT). These are fine for just a single user, but theyāre tied to that user, which isnāt a good practice for deployment in this case.
In this article Iāll show how to use GitHub Apps and Installation Access Tokens (IAT) instead, and go into some detail on how weāve deployed Antora. Our GitHub repositories are private which makes it extra-gnarly.
A friend messaged me late last night with the scary news that Google had emailed him about a ton of spammy subdomains on his own domain.
Any idea how this could have happened, he asked?
Why should the Java folk have all the fun?!
My friend and colleague Gunnar Morling launched a fun challenge this week: how fast can you aggregate and summarise a billion rows of data? Cunningly named The One Billion Row Challenge (1BRC for short), it’s aimed at Java coders to look at new features in the language and optimisation techniques.
Not being a Java coder myself, and seeing how the challenge has already unofficially spread to other communities including Rust and Python I thought I’d join in the fun using what I know best: SQL.
Antora is a modern documentation site generator with many nice features including sourcing documentation content from one or more separate git repositories. This means that your docs can be kept under source control (yay š) and in sync with the code of the product that they are documenting (double yay šš).
As you would expect for a documentation tool, the Antora documentation is thorough but there was one sharp edge involving GitHub that caught me out which I’ll detail here.
AI, what a load of hyped-up bollocks, right? Yet here I am, legit writing a blog about it and not for the clickbait butā¦gaspā¦because it’s actually useful.
Used correctly, it’s just like any other tool on your desktop. It helps you get stuff done quicker, betterāor both.
As a newcomer to Apache Flink one of the first things I did was join the Slack community (which is vendor-neutral and controlled by the Flink PMC). At the moment I’m pretty much in full-time lurker mode, soaking up the kind of questions that people have and how they’re using Flink.
One question that caught my eye was from Marco Villalobos, in which he asked about the Flink JDBC driver and a SQLDataException he was getting with a particular datatype. Now, unfortunately, I have no idea about the answer to this questionābut the idea of a JDBC driver through which Flink SQL could be run sounded like a fascinating path to follow after previously looking at the SQL Client.
Sometimes you might want to access Apache Kafka that’s running on your local machine from another device not on the same network. I’m not sure I can think of a production use-case, but there are a dozen examples for sandbox, demo, and playground environments.
In this post we’ll see how you can use ngrok to, in their words, Put localhost on the internet. And specifically, your local Kafka broker on the internet.
