Hive is a system to distribute data on a global scale, with various desired consistency, replication, and database sharding for linear read and write latency. 1 INTRODUCTION Scaleway is a European cloud provider that runs a large number of cloud-oriented products. One of these prod\u0002ucts is Scaleway Object Storage, a storage API based on Amazon’s S3. There are strict operational requirements on Scaleway’s production in terms of reliability, performance, and efficiency, and to support continuous growth, any plat\u0002form needs to be highly scalable. Reliability is one of the essential requirements because even the..."},{"url":"https://www.scaleway.com/en/blog/building-a-globally-distributed-key-value-store/","final_url":"https://www.scaleway.com/en/blog/building-a-globally-distributed-key-value-store/","title":"Building a distributed Key-Value store to power Object Storage","http_status":200,"content_type":"text/html; charset=utf-8","capture_method":"plain","fetched_at":"2026-06-07T21:17:18.69761+00:00","bytes":161677,"raw_path":"5ae8665bf92a2a87b8f98548803c2996c03bba7e8c8fb2dba103892d7e87853f.html","content_hash":"be3706591a60bf099f7abf80017e37c744af817e4610348bf0faf291a547c958","excerpt_chars":1200,"truncated":true,"excerpt":"Building a distributed Key-Value store to power Object Storage Build • Louis Solofrizzo • 09/09/22 • 7 min read As a cloud provider, we handle a considerable amount of data on a daily basis , especially with our Object Storage products .
