I posted a question on StackOverflow <http://stackoverflow.com/questions/40854529/nesting-avro-schemas> r.e. nesting records in Avro. I think it'll be helpful to make it available here on the mailing list as well, since the Avro community is not very active on SO:
According to this question <https://stackoverflow.com/questions/11764287/how-to-nest-records-in-an-avro-schema> on nesting Avro schemas, the right way to nest a record schema is as follows: { "name": "person", "type": "record", "fields": [ {"name": "firstname", "type": "string"}, {"name": "lastname", "type": "string"}, { "name": "address", "type": { "type" : "record", "name" : "AddressUSRecord", "fields" : [ {"name": "streetaddress", "type": "string"}, {"name": "city", "type": "string"} ] }, } ]} I don't like giving the field the name address and having to give a different name (AddressUSRecord) to the field's schema. Can I give the field and schema the same name, address? What if I want to use the AddressUSRecord schema in multiple other schemas, not just person? If I want to use AddressUSRecord in another schema, let's say business, do I have to name it something else? Ideally, I'd like to define AddressUSRecord in a separate schema, then let the type of addressreference AddressUSRecord. However, it's not clear that Avro 1.8.1 supports this out-of-the-box. This 2014 article <http://www.treselle.com/blog/advanced-avro-schema-design-reuse/> shows that sub-schemas need to be handled with custom code. What the best way to define reusable schemas in Avro 1.8.1? *Note*: I'd like a solution that works with Confluent Inc.'s Schema Registry. There's a Google Groups thread <https://groups.google.com/forum/#!topic/confluent-platform/pey5-AS1NSE> that seems to suggest that Schema Registry does not play nice with schema references. -- *Tianxiang Xiong *| Clojure Engineer *tianxiang.xi...@fundingcircle.com <tianxiang.xi...@fundingcircle.com>* 747 Front Street, Floor 4 | San Francisco, CA 94111
