In Avro 1.7.7, is there a way to specify a *non-empty* array, map, etc.? There doesn't seem to be according to the spec <https://avro.apache.org/docs/1.7.7/spec.html#Maps>.
There are applications in which we mandate that a data format has a non-empty array. It'd be nice if that could be expressed in the schema so data with nonempty arrays fail to serialize (and are thus never put on a Kafka topic). Fail earlier > fail later. Thanks, TX
