Wake up! It's HighScalability time: We've come a long way in 50 years. Or have we? Alan Kay : I believe ARPA spent $ 175,000 of 1968 money for that one demo. That’s probably like a million bucks today. Bill English : What we did was lease two video circuits from the phone company. They set up a microwave link: two transmitters on the top of the building at SRI, receiver/ transmitters up on Skyline Boulevard on a truck, and two receivers at the Civic Center.

An API is an intermediate layer in a software system that is responsible for the data communication between the data source and the Graphical User Interface (GUI) that user’s see. In other words, the API is the business layer of the software that creates a connection between the presentation layer and the data layer.

As mentioned in a previous post, I gave a talk at Percona Live Europe 2018 about system-versioned tables. This is a new MariaDB 10.3 feature, which consists of preserving old versions of a table rows. Each version has two timestamps that indicate the start (INSERT,UPDATE) of the validity of that version, and its end (DELETE, UPDATE). As a result, the user is able to query these tables as they appear at a point in the past, or how data evolved in a certain time range.

They’re guideposts that lead web visitors and app users through a complex set of interactions with their favorite sites and tools.

Ever wondered how hosting companies manage their MySQL database architecture? At Hostinger, we have various MySQL setups starting from the standalone replica-less instances to Percona XtraDB Cluster (later just PXC), ProxySQL routing-based and even absolutely custom and unique solutions which I’m going to describe in this blog post. We do not have elephant-sized databases for internal services like API, billing, and clients.
