We’ve just wrapped up Kafka Summit London… and what an event it was! We met new friends and connected with old ones. We learned from so many folks in the Kafka community. Confluent shared news about Kafka and Confluent Cloud, and also described the upcoming Managed Service for Apache Flink®. If you weren’t able to attend, we’ll be making the talks available online; meanwhile, you can watch the talks from KSL 2022 and Current 2022.

Visit the official Kafka Summit site to watch the keynote and learn more. You can also get started learning Flink with the resources listed below.

Apache Kafka® Resources:

• An oldie but a goodie – “Optimizing Your Kafka Deployment” by Yeva Byzek
• David G. Simmons explains a critical detail about Kafka partitioners
• Learn from Wade Waldron about delivery guarantees in messaging systems

Apache Flink® Resources:

• Apache Flink 101
• Building Apache Flink Applications in Java
• Counting a stream of events with Flink SQL
• Finding the min/max in a stream of events with Flink SQL

Terminal Tip of the Week:

Say I have a file, sed_example.txt, with the following contents:

Cat
Cat
Cat
Dog
Dog
Cat

What if I wanted to replace each ‘Cat’ line with the word ‘Dog’? I could use sed, which is a stream editor. Here’s an example of the syntax I’d use:

❯ sed 's/Cat/Dog/' sed_example.txt
Dog
Dog
Dog
Dog
Dog
Dog

Try it for yourself! (Many thanks to Jeff Bean from Confluent for the suggestion!)! We’ll get into more advanced sed tips in future newsletters.
