To permit null values you must use a union with null.
For example, if you want a field to be either an array of integers or
null, then its type should be:
["null", {"type": "array", "items": "int"}]

For a project we are investigating using Avro as the format for
serializing/de-serializing data. I am currently testing with Avro 1.1.
I have been playing with GenericRecord and I have noticed that if I
define a schema and let's say for example one property is an array, I
will get a NullPointerException if at serialization time I did not put
any data for that particular field aka myRecord.get("array") --> return
null.
So my question is : when using a GenericRecord is it mandatory that all
fields specified in the schema to be non null when serializiation is
happening ?
