This guide details how Sohu News integrated HarmonyOS push notifications—covering DevEco Studio setup, certificate generation, profile configuration, client ID metadata, permission requests, token retrieval, and handling cold‑ and hot‑start push data—using the HarmonyOS NEXT SDK and AppGallery Connect services.
This article outlines the step‑by‑step process for implementing a product promotion push feature in a PHP‑based e‑commerce platform, covering target user identification, promotion table design, message templating, script development, database queries, cron scheduling, and result monitoring to boost user engagement and sales.
The article outlines the design and evolution of an enterprise‑level unified push notification service, detailing its modular to service‑oriented architecture, multi‑channel support, high‑performance non‑functional requirements, and the comprehensive components such as clients, notification, template, distribution, priority queues, adapters, analytics, and database layers.
Tencent’s QQ reminder subscription push system combines push‑pull prefetching, heterogeneous MySQL/Redis storage, delayed‑queue triggers, Redis‑based rate‑limiting, task scattering, message‑queue decoupling, at‑least‑once delivery, and dual‑replica disaster recovery within a dispatcher‑worker architecture to ensure reliable, controllable, low‑latency mass notifications.
The article details Vivo’s push notification platform, describing its evolution from cloud‑based beginnings to a self‑built, three‑region architecture that supports over 1 million concurrent connections, billions of daily messages, and incorporates optimizations such as adaptive heartbeats, advanced load‑balancing, distributed caching, multi‑layer rate limiting, circuit‑breaker mechanisms, and comprehensive content security.
This article details Tencent's application of uplift modeling to optimize QQ Browser push notification volume, covering push system characteristics, causal analysis challenges, a refined S‑learner with metric learning, and resulting DAU improvements, while also addressing practical Q&A on uplift techniques.
Baidu’s Short Video Push System is a distributed platform serving hundreds of millions of users across multiple apps, delivering personalized, real‑time notifications via a modular architecture that includes material and user centers, recall, preprocessing, and delivery services, while optimizations such as activity‑based scheduling, bitmap‑based user segmentation, consistent‑hash frequency control, and protobuf compression boost click‑through rates, scalability, and resource efficiency.
In a high‑throughput mobile push service built on Netty, an off‑heap memory leak was traced to unchecked ChannelOutboundBuffer growth when half‑closed connections remained active but unwritable; fixing it by disabling autoRead on unwritable channels, configuring write‑buffer watermarks, and adding explicit isWritable() checks eliminated the crash and stabilized the system.
HermesX unifies Xianyu’s fragmented push pipelines into a single flow, optimizes content relevance, applies a four‑layer fatigue model, and offers a low‑code management UI, delivering up to 35% less abnormal traffic, 65% lower compute use, and 69% reduced peak latency while paving the way for richer content pools and finer user segmentation.
This article details the background, development steps, and debugging process for enabling dynamic voice playback in iOS push notifications via Notification Service Extension, covering iOS version constraints, integration of system AVSpeechSynthesizer and Baidu offline TTS SDK, code examples, and deployment considerations.
The article presents Hermes, a lightweight and highly reliable mobile push system built with MQTT and Protocol Buffers, detailing its background, technology selection, architecture, heartbeat and reconnection strategies, future optimizations, and practical results that achieve over 99% message delivery rate.
This article presents a comprehensive technical overview of Meitu's personalized push notification pipeline, detailing the evolution of embedding methods (Word2Vec, Airbnb listing embedding, graph embedding), multiple recall strategies (global, personalized, attribute, and content‑based), and a progression of ranking models from logistic regression to field‑wise three‑tower architectures, highlighting their impact on click‑through rates.
From the manual offline 1.0 system to the real‑time, AI‑driven Hermes platform, Xianyu Push evolved through 1.1’s richer feed layout, personalized timing, and IFTTT‑style triggers, ultimately delivering higher click‑through rates, broader scene coverage, and stronger daily active user activation.
This article provides a comprehensive overview of iOS push notification mechanisms, covering remote and local push differences, device token acquisition across iOS versions, silent push constraints, scheduling nuances, and the evolution of notification APIs from iOS 7 to iOS 13, with practical code examples.
