Precision in Every Byte
In this post, we will explore a real-life problem caused by a lack of proper understanding of framework behavior and lock mechanisms. Around three years ago, we were working on a financial app where customers could deposit funds using different payment methods and utilize their balance for purchases simultaneously. Our application was developed in Yii2, …
Back in 2014, I faced a significant challenge that ultimately led me to discover the power of microservices. In this article, I will share my experience of how I stumbled upon microservices to solve a pressing real-world problem and how it transformed our approach to system architecture. I was deeply involved in developing a travel …
As a developer, I often encountered issues with caching where the expiration times were not controllable, leading to unpredictable data updates and challenges in synchronization. This frustration led me to explore ways to make cache expiration more predictable and controllable. The solution I found was to set cache expiration at fixed times, such as 00:00 …
In many web applications, using plain numeric IDs like 100, 200, 300, and 400 can be predictable and expose your system to potential security risks. A simple yet effective approach to mitigate this issue is to encrypt these IDs before displaying them in URLs and decrypt them back in the controllers. This technique ensures that …
In our previous experiment, we explored join operations and table partitioning to manage duplicate bookings in our flight booking system. While these methods were effective, they came with certain complexities and costs. To further optimize our system, we turned to hash-based techniques. This article will walk you through the development and implementation of MD5-based hashing …
When I first tackled the problem of duplicate bookings in our flight booking system, the quickest and simplest solution seemed to be using join operations across our key tables. However, as I delved deeper into the issue, the complexity and cost associated with this approach became evident. Initially, we considered the potential of using fuzzy …
When I first started working in the travel industry, I quickly realized that ensuring the accuracy of passenger data in a flight booking system was critical. Duplicate passenger records frequently led to various issues such as overbooking, customer dissatisfaction, and increased operational costs. Accurate data management became essential for maintaining a seamless and efficient booking …
