----------------------------------------------------------------------
[~barbara] Is there a parser already to convert from the Avro schema to the Avro schema AtlasEntity? I couldn't find it. Could you please help? :)

> Currently the base types in Atlas do not include Avro schemas. It would be nice to add typedef for Avro schema and any associated metadata to support schema evolution.
> * For example, Avro_schema type supports:
> ** All avro types, both primitive and complex, including union types, as fields of schema
> ** All types have doc strings and defaults
> ** A field of a schema can be another schema
> ** Indefinite nesting of records, arrays.
> ** Associated entities array attribute contains pointers to all datasets that reflect the avro schema
> ** Fully expanded avroNotation for use in serDe
> ** Schema evolution features such as isLatest (Boolean) and version number
> * Schema evolution Process
> ** Input: avro schema
> ** Output: new version of avro schema
> ** Compatibility: FULL, BACKWARD, FORWARD, NONE
> ** IsBreakingChange (Boolean): does the change produce an incompatible schema? (ie its compatibility is not “FULL”)
> *
