Yandex open-sources YaFF, a technology that reduce server CPU usage by up to 20%

Published

on

NEW YORK, June 24, 2026 /PRNewswire/ — Yandex has open-sourced YaFF (Yet Another Flat Format), a new technology for efficient data transmission and processing in high-load services. YaFF allows applications to access data without deserialization, helping reduce server CPU usage by up to 20%. For large-scale digital platforms, infrastructure savings can amount to hundreds of millions of dollars annually. The release makes a technology already deployed in Yandex services available to the broader developer community.

Modern digital services continuously exchange large volumes of data between applications, servers, and storage systems. One of the most widely used technologies for this is Protobuf. While efficient for transmitting data, Protobuf requires applications to deserialize data before it can be used. In large-scale systems, that step can consume up to 10% of available CPU resources. Alternatives such as FlatBuffers eliminate this overhead, but often require extensive code changes and migration efforts.

YaFF (Yet Another Flat Format) was developed at Yandex internally to address this trade-off. For teams building high-load backend systems, Protobuf deserialization can become a significant infrastructure cost. YaFF works alongside standard Protobuf infrastructure, allowing applications to access data directly while preserving existing schemas, APIs, and development workflows.

This approach allows organizations to improve infrastructure efficiency without costly rewrites or large-scale migrations. The impact can be especially significant in data-intensive services such as search, advertising, and recommendation systems, where small reductions in CPU usage can free up substantial computing capacity.

YaFF is already used in Yandex’s advertising platform, which handles hundreds of thousands of requests per second. In this production environment, the technology reduced CPU load by 10–20%, helping the company increase capacity while avoiding additional infrastructure costs. YaFF is now available on GitHub under the Apache 2.0 open-source license, with code and documentation for developers interested in testing or contributing to the project as Yandex continues to expand YaFF’s capabilities for large-scale backend systems. 

YaFF expands Yandex’s portfolio of open-source infrastructure technologies developed for large-scale production environments. The company’s open-source projects include Perforator, a continuous profiling system for data centers; YDB, a distributed SQL database; YTsaurus, a distributed data storage and processing platform; SPQR, a PostgreSQL sharding system; and userver, a framework for high-load applications.

Dream ST will be on display as CoolFly highlights flagship Urban, high-performance Dream Pro and its expanding global dealer network

BERLIN, Sept. 6, 2026 /PRNewswire/ — CoolFly, a developer of personal electric aircraft and eVTOL technologies, is showcasing its Dream ST personal aircraft at IFA Berlin 2026, taking place September 4–8 at Messe Berlin.

Dream ST is on display at CityCube Hall B, Booth CCBB-143, in IFA’s Mobility area. While Dream ST is the aircraft physically presented at the show, CoolFly is also introducing its broader product portfolio, including high-performance Dream Pro and flagship Urban.

Dream ST is a lightweight, single-seat electric aircraft designed for personal and recreational flight, featuring a seated configuration and quick-fold design for easier transportation and storage.

Dream Pro extends the platform with greater payload, endurance and performance. It supports a maximum payload of 120 kg, reaches a maximum speed of 100 km/h, and can achieve up to 40 minutes of flight time with a 70 kg pilot onboard, depending on operating and environmental conditions.

Urban, CoolFly’s flagship personal aircraft, features a standing-position configuration and enclosed-propeller architecture, reflecting the company’s effort to create a more intuitive and distinctive personal flight experience.

All three aircraft share CoolFly’s self-developed NA80 flight control system. NA80 uses a dual-redundant architecture with two independent flight-control units, each integrating three aviation-grade inertial measurement units (IMUs). The system continuously monitors aircraft attitude and motion, supports millisecond-level fault detection and failover, and serves as a common technology foundation across CoolFly’s product portfolio.

Dream ST, Dream Pro and Urban have all obtained CE and FCC certifications for applicable product compliance requirements, supporting CoolFly’s continued international expansion.

CoolFly is also actively recruiting dealers, distributors and commercial partners worldwide, with a current focus on Europe, North America, Australia, the Middle East and other key markets.

Prospective partners and media are invited to visit CoolFly at IFA Berlin 2026, CityCube Hall B, Booth CCBB-143.
