Building Scalable Databases: Pros and Cons of Various Database Sharding Schemes – Dare Obasanjo OpiniDatabase sharding is the process of splitting up a database across multiple machines to improve the scalability of an application. The justification for database sharding is that after a certain scale point it is cheaper and more feasible to scale a site horizontally by adding more machines than to grow it vertically by adding beefier servers.

Sharding your database I’m increasingly encountering users on Heroku that are encountering the need to shard their data. For most users this is something you delay as long as possible as you can generally go for sometime before you have to worry about it. Additionally scaling up your database is often a reasonable approach early on and something I encourage as a starting point as scaling up is easy to do with regards to databases. However, for the 1% of users that do need to shard when the time comes many are left wondering where to start, hence the following guide. March 24, 2022 at 12:34AM
The Ultimate Guide to Real-Time Lane Detection Using OpenCV – Automatic Addison In this tutorial, we will go through the entire process, step by step, of how to detect lanes on a road in real time using the OpenCV computer vision library and Python. By the end of this tutorial, you will know how to build (from scratch) an application that can automatically detect lanes in a video stream from a front-facing camera mounted on a car. You’ll be able to generate this video below. March 22, 2022 at 03:46PM
