title: "Déploiement progressif du code de classement chez Glean"

Iterative and frequent releases are a powerful way to enhance the performance of ranking systems. This deployment strategy, however, introduces significant challenges when working with stateful services that must maintain information across sessions. Glean has developed a specialized methodology for progressively rolling out new ranking code without disrupting these complex environments. This approach ensures that updates can be deployed safely and effectively, allowing for continuous improvement while maintaining service stability.
