Sharing insights and experiences from Dada Group's R&D department on product refinement and technology advancement, connecting with fellow geeks to exchange ideas and grow together.
The article describes how Dada Group created the Tianhe platform to centralize, standardize, and automate massive data‑tracking (埋点) requirements across multiple product lines, detailing its goals, architecture, core functions, current status, and future development directions.
This article details JD Daojia's mobile‑side engineering practices, covering a unified Flutter SDK, resource management, state‑management patterns, precise exposure tracking, and a custom dynamic‑update mechanism that enables hot‑swapping of Flutter binaries and assets on Android.
This article describes how Dada Group tackled rapid micro‑service growth by designing a language‑agnostic, lightweight service governance and traffic routing engine that uses Consul metadata, configurable routing rules, and link‑based isolation to enable online pressure testing, parallel development, hot‑cold service separation, gray releases, and dynamic rate limiting.
This article details Dada Group's development of the Dada Flink SQL engine, describing its background, architecture, parser design, dimension‑table join strategies, numerous enhancements such as HA support, Kafka keyword handling, metadata integration, Redis and ClickHouse sinks, BINLOG simplification, and future migration plans toward Flink 1.10.
The article describes how Dada rebuilt its log processing pipeline using Kubernetes mixed deployment, Filebeat for automated collection, Storm for efficient parsing, and Elasticsearch cold/hot nodes to handle over 130 billion daily log entries and 300TB storage.
This article details how a mobile team adopted Flutter for the majority of its app development, compares it with React Native, outlines training, collaborative and hybrid development strategies, presents iOS and Android integration steps, and shares the performance, debugging, and disaster‑recovery benefits achieved.
By migrating all Dada front‑end projects to an automated CI build platform, introducing Docker volume caching and internal npm mirrors, we eliminated manual steps, reduced build time by more than half, and saved roughly 40 hours of developer time each month.
This article describes how to implement a traffic management system using service isolation to address challenges in full-link pressure testing, parallel feature testing, and online gray release.
This article explains the motivations for upgrading a mobile event‑logging framework, describes the native C‑based log system design and implementation with code examples, addresses precise exposure challenges, and presents a hybrid stack solution for RN/Flutter integration along with data degradation strategies.
This case study presents the LaiLaiTui project for JD Daojia, detailing its background, extensive user research with 685 questionnaires, usability testing, interview findings, visual style exploration, product structure, and future planning to improve promotion efficiency and user experience.
