很多团队的网络监控并不算差。 链路可用率有、接口带宽有、CPU 和内存有、异常告警也接进了企业微信、飞书和短信。但真正出了事，复盘时还是会出现同一句话：当时知道出问题了，但没有把现场留住。 这就是为什么越来越多团队开始关注网络回溯分析系统。 它解决的不是“能不能看到告警”这个初级问题，而是更关键的两个问题： 告警发生时，能不能快速还原到底是哪一段流量、哪一条路径、哪一种会话出了问题 事故结束后，能不能基于证据复盘，而不是靠聊天记录和印象拼凑过程 对云上和混合云场景来说，这件事尤其重要。因为链路更长、设备更多、路径更动态，很多故障不是“持续坏”，而是短时抖动、瞬时拥塞、路径切换、策略误命中。如果没有回溯能力，排障就很容易沦为赛后猜谜。 这篇文章不讲空洞概念，直接从一线运维视角拆清楚：云上网络回溯分析系统到底该怎么建，应该覆盖哪些能力，落地时最容易踩哪些坑。 先说结论： 传统监控擅长发现“异常
If your Flutter app offers any third-party login on iOS — Google, Facebook, anything — Apple's App Review guideline 4.8 forces you to also offer Sign in with Apple. That part is non-negotiable. .p8 keys, capabilities, entitlements, deep links — and most of it is only documented across three or four different Apple and Supabase pages that don't quite agree with each other. This is the guide I wis
Supabase Edge Functions run on Deno Deploy and are far more capable than simple REST handlers. This guide covers three advanced patterns every indie developer should know: streaming responses (for LLM integrations), WebSocket upgrades (for real-time features), and background jobs using EdgeRuntime.waitUntil. The most common use case is streaming LLM output without blocking the client. // supabase/
Supabase Realtime streams PostgreSQL changes to clients over WebSocket. Combine it with Flutter and you can ship live notifications, "who's online" indicators, and collaborative editing in dozens of lines of code. This guide covers all three channel types — Postgres Changes, Presence, and Broadcast — with production-ready examples. Type Use Case Data Source Postgres Changes React to INSERT/
Power BI is a powerful business analytics service developed by Microsoft that empowers users to visualise data and share interactive dashboards across their organisation. While Power BI can handle data from various sources, its true potential is unleashed when connected to robust data sources like SQL databases. SQL databases—such as PostgreSQL, MySQL, and SQL Server—are the industry standard for
If you've been building with Supabase, you know their Storage API is fantastic for web apps. But sometimes, you just need your files on your local machine—whether for a manual backup, bulk editing, or migrating data. While you could write a script using the Supabase SDK, there is a much faster, "no-code" way to manage your files like a Pro: Cyberduck. Note: Cyberduck is an official Supabase partne
Supabase Webhooks Deep Dive — Database Triggers, pg_net & Edge Function Patterns Supabase Webhooks let you react to INSERT/UPDATE/DELETE events on any table and call an external endpoint or an Edge Function automatically. Under the hood it uses the pg_net extension to fire non-blocking HTTP requests directly from PostgreSQL triggers. DB change → pg_net (async HTTP) → Edge Function or external en
The problem: too many clients, too few discovery hooks We expose Supabase Edge Functions as MCP (Model Context Protocol) servers. The clients that hit them are heterogeneous — Claude Desktop, Codex CLI, Cursor, VS Code Continue, a couple of in-house browser extensions. None of them ship with a hard-coded "use WorkOS AuthKit, scope is tool:ai_chat, audience must contain urn:jibun:tool:<tool>" rec
