Hermes Performance System: Architecture and Implementation for O2O Business
The article presents Hermes, Meituan’s O2O performance management platform for travel, detailing its six‑module, four‑engine architecture—including data, incentive, rule, calculation, and scheduling engines—while highlighting technical innovations such as two‑level caching, work‑stealing producer‑consumer processing, Map‑Reduce‑style calculations, and future AI‑driven enhancements.
This article introduces Hermes, a performance management system developed by Meituan for its O2O business, particularly in the travel sector. The system addresses challenges in managing large-scale offline teams and complex performance calculations.
The article outlines the system's architecture, which includes six modules and four engines: data engine, incentive management, indicator configuration, rule engine, calculation engine, and scheduling engine. It details how the system handles massive data volumes, flexible performance schemes, and intelligent target setting.
Key technical solutions include a two-level caching structure, Producer-Consumer pattern with work-stealing algorithm for task processing, and a Map-reduce inspired calculation engine. The system also features data pre-loading, asynchronous operations, and comprehensive permission controls.
The authors discuss future plans to enhance the system's intelligence using data mining and machine learning, and to improve data source management. The article concludes with author introductions and recruitment information for those interested in data product tool development.
