System Design Meetup

Kafka and RabbitMQ, and the future of this Medium.

Hi folks,

For a bit over a year now I’m hosting the System Design Meetup. The last episode, about Kafka and RabbitMQ, was quite interesting, and I’ve cut a few shorts from it, here. Teasers:

• An intro to Kafka as the product, in five minutes.
• An intro to RabbitMQ and Erlang, all under ten minutes.
• Why append-only queues are always faster than DB transactions, in two minutes.
• How Kafka consumers works, leveraging consumer groups in two ways, ten minutes.
• Using heartbeats to re-create total order from partial order, three minutes.

If you want to join the meetup, this link should take you to our Slack.

Not much else to say. Medium followed the path of Quora, which followed the footsteps of Facebook : paid beats organic.

I’ve moved to Substack, not necessarily because I believe it is better, and not because I plan to monetize my posts, but largely because I like Substack’s policy of allowing one to export the list of subscribers’ emails. Good incentives always beat good decisions in my book, and, with such a policy (for as long as it is in place, at least), I am quite confident the platform will be growing.

Including an image here because Medium doesn’t let me to it later, during publishing. Hehe.

Thanks,
Dima
