If we were to select the most important MySQL setting, if we were given a freshly installed MySQL or Percona Server for MySQL and could only tune a single MySQL variable, which one would it be? It has always bothered me that “out-of-the-box” MySQL performance is subpar: if you install MySQL or Percona Server for MySQL in a new server and do not “tune it” (as in change default values for configuration settings), it just won’t be able to make the best use of the serve

In this post, you will learn how to create a Docker image for your GraalVM native image. By means of some hands-on experiments, you will learn that it is a bit trickier than what you are used to when creating Docker images. Enjoy! Introduction In a previous post , you learned how to create a GraalVM native image for a Spring Boot 3 application. Nowadays, applications are often distributed as Docker images, so it is interesting to verify how this is done for a GraalVM native image.

The notion that artificial intelligence will help us prepare for the world of tomorrow is woven into our collective fantasies. Based on what we’ve seen so far, however, AI seems much more capable of replaying the past than predicting the future. That’s because AI algorithms are trained on data. By its very nature, data is an artifact of something that happened in the past.

When talking about the benefits and use cases of ProxySQL with clients, one feature I generally reference is the query rewrite engine. This is a great feature that is often used for sharding (I’ve written about this in the past at Horizontal Scaling in MySQL – Sharding Followup ). Another use case I reference is “temporary application fixes.” While this is definitely a valid use case, I hadn’t personally come across an issue in the wild where the application fix was

In particular, there is usually an excess of solar energy during the day that makes the grid mix better than at night.

Binary Javascript Object Notation (BSON) is a bin­ary-en­coded seri­al­iz­a­tion of JSON documents. JSON is easier to understand as it is human-readable, but compared to BSON, it supports fewer data types. BSON has been extended to add some optional non-JSON-native data types, like dates and binary data. MongoDB stores data in BSON format both internally and over the network.

This process involves comparing a baseline application or website version with a current version and checking for visual differences. During visual regression testing, images of the application or website are captured and compared using specialized tools highlighting differences.

The life of a jumbo chunk MongoDB marks a chunk as “jumbo” when it grows past the configured maximum chunk size. This value defaults to 128 MB since MongoDB 6.0 (it used to be 64 MB before). The most common reason for jumbo chunks to appear is when the auto-splitter process cannot find a way to split a chunk. This can happen, for example, when all documents in the chunk contain the same shard key.
