Demonstrating the raw speed of modern hardware

While working on a demo for processing change events from Postgres with Apache Flink, I noticed an interesting phenomenon: A Postgres database which I had set up for that demo on Amazon RDS, ran out of disk space. The machine had a disk size of 200 GiB which was fully used up in the course of less than two weeks. Now a common cause for this kind of issue are replication slots which are not advanced: in that case, Postgres will hold on to all WAL segments after the latest log sequence number (LSN) which was confirmed for that slot. Indeed I had set up a replication slot (via the Decodable CDC source connector for Postgres, which is based on Debezium). I then had stopped that connector, causing the slot to become inactive. The problem was though that I was really sure that there was no traffic in that database whatsoever! What could cause a WAL growth of ~18 GB/day then?

In 2022, disk I/O is very fast, and not usually the performance bottleneck in programs. This article digs into some numbers.

As of late, concerns about the future of Twitter have caused many of its users to seek alternatives. Amid this upheaval, an open-source microblogging service called Mastodon has received a great deal of attention. Mastodon is not reliant on any single company or central authority to run its servers; anyone can run their own. Servers communicate with each other, allowing people on different servers to send each other messages and follow each other's posts. Mastodon doesn't just talk to itself, though; it can exchange messages with anything that speaks the ActivityPub protocol. There are many such implementations, so someone who wants to deploy their own microblogging service enjoys a variety of choices.

By identifying roles, resources and how they map together, you can implement an efficient system that ensures your users and applications are secure.
