Deep Dive: Fluent Bit
summary
Fluent Bit is a C-based, single-threaded log router that uses an event loop and lightweight coroutines to perform nonblocking network I/O, MessagePack for fast in-memory records, and a pluggable API for inputs, filters and outputs. It reports 13 million deployments recently, typically runs around 500 KB footprint for idle agents, and ships MessagePack binary format, Lua filters, Kubernetes metadata enrichment, and planned filesystem buffering so it survives backend outages and works at cloud scale.
