> Following AVRO-1385, it appears Avro's resolving decoder performs decode-time compatibility check, ie. per datum instance compatibility check, as opposed to per schema compatibility check.
> For our use-cases, we need to determine whether all datum instances of a particular writer schema will always succeed in being decoded using a given reader schema.
