AVRO-2748: Refactor Schema Matching (#861)
Move schema matching into schema objects because each type knows its matching
logic best.
> python schema resolution occurs on every read
> ---------------------------------------------
>
> Key: AVRO-2748
> URL: https://issues.apache.org/jira/browse/AVRO-2748
> Project: Apache Avro
> Issue Type: Bug
> Components: python
> Affects Versions: 1.9.2
> Reporter: Erik Erlandson
> Priority: Minor
>
> In python, the schema resolution appears to be happening on each read
> operation. I'm not an avro expert but in my perusing through the python io
> code I haven't yet noticed a reason that the schema resolution couldn't
> happen once up front, during the construction of DataFileReader, when it
> first loads the write_schema.
