FlatBuffers does the trick as a better replacement to ProtoBuf when running in some resource-critical devices. We were working on a project that leverage Arrow IPC (internally FlatBuffers) and shared memory to collect metrics on edge devices with limit CPU and memory, hopefully we can open source it soon.

But in this case the format is defined by [Prometheus](https://github.com/prometheus/prometheus/blob/main/prompb/re...) and we just adopt that.
