If anyone is familiar with Avro-based schemas, I just noticed an issue in one of my jobs that started throwing our these warnings (with generic types disabled):

Field MySchema#property will be processed as GenericType. Please read the Flink documentation on "Data Types & Serialization" for details of the effect on performance and schema evolution.

These are Avro-generated Java objects (via the Maven Avro plugin) using AVSC files. It appears these are being thrown only for array-based fields, but in the interest of performance I’m trying to make sure that these are handed efficiently. What’s the best way to go about this?
