How do you get the data you need to build the models while also respecting data privacy? The answer is pre-labeled data sets.

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.
