Mecanum wheel Lidar High-precision camera myAGV is jointly developed by Elephant Robot and Huaway. The manipulator uses mycobot and loads camera Eye-in-Hand design. myAGV adopts Mecanum wheel + lidar + high-precision camera. Control mode: autonomous navigation, handle control, keyboard control, etc.

There are many ways to scale out your database; many of these techniques require advanced management and expensive add-ons or editions. Database sharding is a flexible way of scaling out a database. In this presentation, Jeremiah Peschka explains how to scale out using database sharding, covers basic techniques, and shares some of the pitfalls. This...

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.

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.
