In part 1 of this blog series , we explored the concept of business observability, its significance, and how real-time visibility aids in making informed decisions. In part 2, we’ll show you how to retrieve business data from a database, analyze that data using dashboards and ad hoc queries, and then use a Davis analyzer to predict metric behavior and detect behavioral anomalies.

Parallel garbage collector (Parallel GC) is one of the oldest Garbage Collection algorithms introduced in JVM to leverage the processing power of modern multi-core systems. Parallel GC aims to reduce the impact of GC pauses by utilizing multiple threads to perform garbage collection in parallel. In this article, we will delve into the realm of Parallel GC tuning specifically.

Recently, I had to use Ansible to implement infrastructure as code. Initially, I used Windows Subsystem for Linux (WSL) to run the Ansible playbooks. The advantage of WSL is that it gives one a Linux shell on a Windows machine without any further ado. However, I found that WSL has this tendency to go haywire and use system resources such as CPU and RAM to the max.

Kerberos is a secure authentication protocol for networked systems. It was developed at the Massachusetts Institute of Technology (MIT) and was first released in the 1980s. The protocol provides secure authentication of users and services, allowing them to communicate over an insecure network such as the Internet. Kerberos uses secret-key cryptography to secure communications and relies on a trusted third-party authentication server known as the Key Distribution Center (KDC).

A join in SQL combines columns from one or more tables to extract the required data. When used effectively, joins can simplify queries and save a lot of time. In this blog, we will look into an easy way to visualize the data captured by various joins using Venn diagrams and their SQL equivalent. Some of these joins are only available natively in some relational databases; for the sake of simplicity, we will only consider the most widely used open-source databases in this blog- MySQL and PostgreS

Functional indexes are found in both of Percona’s relational databases, MySQL and PostgreSQL, but they are probably the least used and most understood index type, aside from geospatial. You may also hear this type of index being called Index on expression. So, what is a functional index? Definitions The examples below use MySQL, but it is helpful to check their competition’s documentation to help explain what a functional index is.
