Platform Engineering Teams Done Right…

Adrian Cockcroft

Picture by Adrian — Ka’anapali sunset 2023 There’s been a lot of discussion about platforms recently, I talked about why I think it’s a current hot meme on the WTF Podcast with Charles Humble recently, and Sam Newman just wrote a blog post “ Don’t call it a platform ”. What I want to cover in this blog post is how I think platforms should be structured, and why it’s always plural, there isn’t one platform or one platform team.

How Bloom Filters Work in MyRocks

Percona

Bloom filters are an essential component of an LSM-based database engine like MyRocks. This post will illustrate through a simple example how bloom filters work in MyRocks. Why? With MyRocks/RocksDB, data is stored in a set of large SST files. When MyRocks needs to find the value associated with a given key, it uses a bloom filter to guess if the key could potentially be in an SST file.

Top Three Docker Alternatives To Consider

Docker is a containerization technology that allows developers to package and deploy applications in lightweight, portable containers. These containers are isolated from the host operating system, which makes them portable across different environments and eliminates the “works on my machine” problem. Docker is a popular platform for creating and managing containerized applications; however, several alternatives for Docker can also be used for this purpose.

Node metrics available inside of a container

Percona Community

Several people asked me this question: Could we get Node metrics inside of a container? Usually, this comes from the fact that PMM or standalone people run node_exporter inside a container. PMM does it as a sidecar along with many other exporters to monitor DBs, and node_exporter comes out of the box as a default one. So people could see accurate data on dashboards, like Memory and CPU, that node_exporter reads inside the container.
