Improving Performance in a Hierarchical SQL Structure

Featured Imgs 23

This article will show how column propagation can represent a straightforward approach to improving query performance when dealing with a hierarchical data structure.

We'll do this with a real-world scenario based on a data-driven project involving a live data website developed for a startup operating in the sports industry. You'll learn everything you need to know about column propagation as a solution to the performance issues inherent in hierarchical SQL table structures. Let's begin.

What is Education Q&A?

Featured Imgs 11

Search Appearance in Google Search Console performance report shows a line item "Education Q&A".

Does anyone know how this differs from "Q&A rich results"?

Education Q&A has a really good search position compared to Q&A rich results, which is the majority of our pages.

When I look at top pages, I'm not really seeing a big distinction that would make them stick out as specifically education-related.

Enabling Business Transaction Monitoring for App Connect Enterprise

Featured Imgs 23

Introduction

IBM App Connect V12 introduced a new capability called Business Transaction Monitoring (BTM) which allows the user to record a message throughout its lifecycle and determine its outcome.

What Is Transaction Monitoring?

Transaction monitoring involves surveying each message that passes through your flows and ruling whether it was transmitted successfully or had failed to reach the destination. Monitoring each transaction through an integration ensures that developers are notified when a system fails, and output has not been received. However, simply monitoring if a message has reached its destination does not help identify the specific problem, which is where Business Transaction Monitoring can help.

Building a 32-Core Raspberry Pi Cluster From Scratch

Featured Imgs 23

A Raspberry Pi is a mini-computer board to which you can connect a monitor, mouse, and keyboard, and install a Linux-based operating system with a GUI. Or you can use it in “headless” mode with no GUI and run, for example, a database server. There are many usages you can give a Raspberry Pi—from building a Minecraft server to smart mirrors, the possibilities are endless.

Since I started to discover MariaDB and learned about database clusters, Distributed SQL, and Xpand, the idea of building a Raspberry Pi cluster has been in the back of my head. A cluster like this is a great way to experiment with distributed systems.

When Disaster Strikes: Production Troubleshooting

Featured Imgs 23

Tom Granot and I have had the privilege of Vlad Mihalcea’s online company for a while now. As a result,  we decided to do a workshop together talking about a lot of the things we learned in the process. This workshop would be pretty informal ad-hoc, just a bunch of guys chatting and showing off what we can do with tooling. 

In celebration of that, I thought I’d write about some of the tricks we discussed amongst ourselves in the past to give you a sense of what to expect when joining us for the workshop but also a useful tool in its own right.
