“A modern standard for event-oriented data”. Avro schema, events have time and type, schema is external and not part of the Avro stream. ‘a modern standard for representing event-oriented data in high-throughput operational systems. It uses existing open standards for schema definition and serialization, but adds semantic meaning and definition to make integration between systems easy, while still being size- and processing-efficient. An Osso event is largely use case agnostic, and can represent a log message, stack trace, metric sample, user action taken, ad display or click, generic HTTP event, or otherwise. Every event has a set of common fields as well as optional key/value attributes that are typically event type-specific.’
