An epochal breakthrough in data processing is unleashing the true potential of web applications.

On March 18, the American corporation Microsoft presented Garnet — a new caching system designed to speed up applications and services. Created by a large team of researchers, Garnet is the result of many years of work to improve data storage efficiency in the face of growing demand for interactive web applications and services. Now the system is available in the public domain, which will allow developers to make changes to it and expand its functionality.

Garnet has already found application in various Microsoft projects, including the Windows & Web Experiences, Azure Resource Manager, and Azure Resource Graph platforms. Opening the source code of the system provides developers with opportunities to improve its performance and functionality, as well as encourages academic research and collaboration in this area.

Garnet differs from traditional caching systems in that it supports a wide range of APIs, including operations with primitive data types, analytical structures, and complex data types. This provides a significant improvement in scalability and throughput when dealing with a large number of client connections and small data packets.

The system is developed on the basis of the latest technologies .NET, which makes it cross-platform, extensible, and modern. Garnet provides high performance on both Linux and Windows, thanks to the efficient use of .NET libraries.

Comparison of Garnet with the leading open caching systems showed a significant advantage of the new system in terms of speed and scalability. The tests were performed on Azure VMs using a specialized benchmarking tool. The experimental results demonstrate better throughput and lower latency when processing requests, especially in conditions of high load and different data packet sizes.

The Garnet architecture includes advanced solutions for processing network requests and interacting with the data warehouse. The system uses a fast and modular network architecture, supports secure TLS connections, and offers advanced capabilities for working with data storage, including scalability, support for different storage levels, and fast recovery from failures.

Microsoft plans to continue actively developing Garnet, including adding new features and improvements. The company also hopes for the active participation of the developer community in the project, which will expand the possible interaction with the community to further expand the capabilities and improve the efficiency of the system.
