Axiom

Axiom 是面向机器数据的日志与事件平台，架构是流式写入加读时解析模式：日志进来不做字段映射，查询时再解析，因此不必事先定义 schema，也不会因为字段变动而丢数据。查询语言 APL 按顺序处理数据，写法接近管道，日志与指标各有一套引擎。常见的用法是吧 CDN、无服务器函数与边缘日志整批进来，按需查单个请求的全链路，再把结果挂到看板或告警上。有免费额度，也能自托管。 🔗 文档: https://axiom.co/docs

Axiom is a log and event platform for machine data built on stream-oriented ingest with schema-on-read: records arrive without field mapping and are parsed at query time, so no schema has to be declared up front and nothing is dropped when fields change shape. The APL query language processes data sequentially in a piped style, with separate engines for logs and metrics. The common pattern is to route CDN, serverless and edge logs in bulk, query a single request's full path on demand, then hang the result on dashboards or alerts. There is a free tier and a self-hosted option. ⭐ Notable: schema-on-read ingest, APL query language, edge and serverless log routing 🔗 Docs: https://axiom.co/docs
