Lightning Memory-Mapped Database (LMDB)

I've linked to the Wikipedia article because it has the most useful information for a first encounter with the technology within a single page.

In comparison, the official page [0] has rather janky styles and a very enterprise-y design, which I think might turn off some people from giving it a fair chance. With that said, the technical information page [1] actually has a lot of good links including a list of some of the big projects using LMDB and a list of bindings for all major programming languages.

There's also their documentation page [2], although it looks like it hasn't been updated since 2015. For anyone interested in trying it out, you'll want to read through their Getting Started [3] page. Many of the binding also include great docs, which might be a viable alternative for someone that's not as comfortable or experienced with C.

Many of their blog posts [4] are worth reading if you're interested in its design and the different tradeoffs made.
