Lib.rs

A high-performance storage engine for modern hardware and platforms.

PhotonDB is designed from scratch to leverage the power of modern multi-core chips, storage devices, and operating systems.

Features:

• Latch-free data structures, scale to many cores.
• Log-structured persistent stores, optimized for flash storage.
• Asynchronous APIs and efficient file IO, powered by io_uring on Linux.

This crate provides three sets of APIs:

• Raw: a set of low-level APIs that can run with different environments.
• Std: a set of synchronous APIs based on the raw one that doesn't require a runtime to run.
• Photon: a set of asynchronous APIs based on the raw one that must run with the PhotonIO runtime.

The Photon APIs are the default and are re-exported to the top-level module for convenience.
