Erik Erlandson commented on AVRO-2474:
--------------------------------------
I have written up a draft of an Avro Enhancement Proposal, that describes a
roadmap where unit expression parsing conversion is done as a part of resolving
reader schemas with writer schemas:
[Avro Enhancement Proposal (AEP): Unit
Metadata|https://docs.google.com/document/d/1IeVAtf6YcAAn35D4jmFQJjPpEMgEu79wWVMW37KvNps/]
> Support a "unit" property of schema fields
> ------------------------------------------
>
> Key: AVRO-2474
> URL: https://issues.apache.org/jira/browse/AVRO-2474
> Project: Apache Avro
> Issue Type: Improvement
> Components: spec
> Affects Versions: 1.9.0
> Reporter: Erik Erlandson
> Priority: Major
>
> Recently I have been experimenting with avro schema that are extended with a
> "unit" field. By "unit" I mean expressions like "second", or "megabyte" -
> that is "units of measure".
>
> I received some community interest in making this concept "first class" for
> avro; I'm filing this JIRA to track the idea.
>
> I delivered a short talk on my experiments at Berlin Buzzwords, which can be
> viewed here:

>
> I also wrote a short blog post that may be faster to ingest:
> [http://erikerlandson.github.io/blog/2019/05/23/unit-types-for-avro-schema-integrating-avro-with-coulomb/]
