Aggregated on: Wed Jul 12 2023 17:01:09 GMT+0000 (Coordinated Universal Time)

As developers working with third-party REST APIs, it is often necessary to store the request and response details for potential future reference, especially when issues arise. This could serve as invaluable data to liaise with third-party vendors, providing a first-hand look at the raw interaction that occurred. In my role, I am constantly orchestrating API’s with multiple partner services. Therefore, I sought a generic solution to store these third-party API requests and responses seamlessly. The Spring Framework's RestTemplate, a widely used synchronous HTTP client, proves to be a handy tool for consuming RESTful services.

Aggregated on: Wed Jul 12 2023 16:46:09 GMT+0000 (Coordinated Universal Time)

This article aims to provide a reference for non-tech companies who are seeking to empower their business with data analytics. You will learn the basics about how to build an efficient and easy-to-use data system, and I will walk you through every aspect of it with a use case of Apache Doris, an MPP-based analytic data warehouse. What You Need This case is about a ticketing service provider who wants a data platform that boasts quick processing, low maintenance costs, and ease of use, and I think they speak for the majority of entry-level database users. A prominent feature of ticketing services is the periodic spikes in ticket orders, you know before the shows go on. So, from time to time, the company has a huge amount of new data rushing in and requires real-time processing of it so that they can make timely adjustments during the short sales window. But at other times, they won't want to spend too much energy and funds on maintaining the data system. Furthermore, for a beginner in digital operation who only require basic analytic functions, it is better to have a data architecture that is easy to grasp and user-friendly. After research and comparison, they came to the Apache Doris community, and we help them build a Doris-based data architecture.

Building for Failure: Best Practices for Easy Production Debugging

Aggregated on: Wed Jul 12 2023 16:16:09 GMT+0000 (Coordinated Universal Time)

Quite a few years ago, I was maintaining a database-driven system and ran into a weird production bug. The column I was reading from had a null value, but this wasn’t allowed in the code, and there was no place where that value could have been null. The database was corrupt in a bad way, and we didn’t have anything to go on. Yes, there were logs. But due to privacy concerns, you can’t log everything. Even if we could, how would we know what to look for? Programs fail. That’s inevitable. We strive to reduce failures, but failure will happen. We also have another effort, and it gets less attention: failure analysis. There are some best practices and common approaches, most famously logging. I’ve often said before that logs are pre-cognitive debugging, but how do we create an application that’s easier to debug?
