Avro streams

An Avro stream file holds records shaped like streamed data: each record names one channel, with its own timestamps, values and tags. To write one, see Write a file, and for writers in other languages, the schema.

from nominal.core import NominalClient

client = NominalClient.from_profile("default")
dataset = client.create_dataset("Flight telemetry")
