title: Defaults for nested records in an Avro schema
body: <p>This question/answer (<a href="https://stackoverflow.com/questions/11764287/how-to-nest-records-in-an-avro-schema">How to nest records in an Avro schema?</a>) clears things up on how to nest complex types (records in this case). However, I'm wondering if anyone knows how to have default values for record types. I'm getting errors when in the example shown in the above question, the address is missing and I'd prefer avro to default it to an empty dictionary or at the very least to an empty String - instead of me having to default it in advance.</p>
