Feature Flags and Canary Releases in Microservices

Aggregated on: 2024-03-11 18:12:16

Feature flags are commonly used constructs and have been there for a while. But in the last few years, things have evolved and feature flags are playing a major role in delivering continuous risk-free releases. In general, when a new feature is not fully developed and we still want to branch off a release from the mainstream, we can hide our new feature and toggle it off in production. Another use-case is when we want to release our feature to only a small percentage of users, we set the feature 'on' for a segment/geography and set it 'off' for the rest of the world. The capability to toggle a feature on and off without doing a source code change gives the developer an extra edge to experiment with conflicting features with live traffic. Let us deep dive into more details about feature flags and an example implementation in Springboot. Things To Consider When We Are Introducing a New Feature Flag Establish a consistent naming convention across applications, to make the purpose of the feature flags easily understandable by other developers and product teams. Where to maintain feature flags? In the application property file: Toggle features based on environment. Useful for experimenting in development while keeping features off in production. In configuration server or vault: Let's imagine you are tired after a late-night release, and your ops team calls you at 4 am, to inform you the new feature is creating red alerts everywhere in monitoring tools, here comes the Feature toggle to your rescue. First, turn the feature 'off' in the config server and restart compute pods alone, In database or cache: Reading configs or flag values from a database or an external cache system like Redis, you don't have to redeploy or restart your compute, as the values can be dynamically read from the source at regular intervals, pods get updated value without any restart. You can also explore open-source or third-party SDKs built for feature flags, a handful of them are already in the market. They also come with additional advantages that help in the lifecycle management of feature flags.

A Developer's Guide to Database Sharding With MongoDB

Aggregated on: 2024-03-09 03:12:14

As a developer, you may encounter situations where your application's database must handle large amounts of data. One way to manage this data effectively is through database sharding, a technique that distributes data across multiple servers or databases horizontally. Sharding can improve performance, scalability, and reliability by breaking up a large database into smaller, more manageable pieces called shards. In this article, we'll explore the concept of database sharding, discuss various sharding strategies, and provide a step-by-step guide to implementing sharding in MongoDB, a popular NoSQL database.

Why Do We Need Databases and SQL?

Aggregated on: 2024-03-09 00:27:14

SQL has a long and proven history. It has survived the fuss around NoSQL. Even if it is not perfect, it has been demonstrated to be the best available language for data. This is no surprise! The story began in the 1960s with the development of databases—an era marked by the introduction of the Integrated Data Store (IDS) at General Electric. However, it was Edgar Codd’s relational model that revolutionized data handling. His model, which turned data into a series of tables (or, more strictly, relations), has influenced database systems ever since. This era also saw the birth of SQL (Structured Query Language), which became the standard language for interacting with relational databases, including MariaDB and others. The Utility of Relational Database Systems So, why do we need all this database stuff? Let’s imagine you’re building an app, maybe a simple to-do list to keep track of your daily tasks. Initially, you might think, “Why not just save each task directly to a file?” After all, my programming language has constructs and libraries to save and read data from disk. Also, implementing this seems straightforward: create a task, write it to a file, delete a task, and remove it from the file. These are good points; however, as your app gains traction, users start to aggregate, and suddenly, you have thousands of users trying to add, delete, and modify tasks simultaneously. At this point, the simplicity of files becomes fragile. Imagine one user is updating a task at the exact moment another tries to delete it. Or maybe two users are editing the same task at the same time. With a simple file system, you’re likely to end up with corrupted or lost data because there’s no inherent mechanism to handle such conflicts.

Performing Advanced Facebook Event Data Analysis With a Vector Database

In today's digital age, professionals across all industries must stay updated with upcoming events, conferences, and workshops. However, efficiently finding events that align with one's interests amidst the vast ocean of online information presents a significant challenge. This blog introduces an innovative solution to this challenge: a comprehensive application designed to scrape event data from Facebook and analyze the scraped data using MyScale. While MyScale is commonly associated with the RAG tech stack or used as a vector database, its capabilities extend beyond these realms. We will utilize it for data analysis, leveraging its vector search functionality to analyze events that are semantically similar, thus providing better results and insights.

What’s a Resume For?

Aggregated on: 2024-03-08 22:27:14

In the course of talking about job hunting with friends, colleagues, and randos on Slack and elsewhere, I end up talking about resumes. A lot. There is, (in my (not so) humble) opinion, a sizeable misunderstanding about what resumes are, what they do, how they should look, the effort one should (or shouldn’t) put into creating them, and more. Given the current period of churn in the tech industry and the resulting uptick in the frequency with which I’m having these types of conversations, I decided to commit to what’s become a standard part of my “so you’re looking for a new job?” shpiel to paper (or at least electrons).

Why GraphQL Is a Superior Choice for Building Microservices?

Aggregated on: 2024-03-08 21:27:14

In the evolving landscape of software development, the debate between using REST and GraphQL for building microservices is becoming increasingly relevant. Both technologies have their proponents and critics, but when it comes to the specific needs of microservices architectures, GraphQL emerges as the clear front-runner. Here's why. Understanding the RESTful Concerns Popularity vs. Limitations While REST has been the go-to API style for many years, lauded for its simplicity and general applicability, its limitations become glaringly apparent in the context of microservices. These limitations include:
