How to join two records?

[Roger Hoover]

Hi,

If I have a two records of type A and B as below and want to join them
similar to "SELECT *" in SQL to produce a record of type AB, is there an
simple way to do this with Avro without writing code to copy each field
individually?  It's like a reverse projection.  I want to take to disjoint
projections of AB and merge them to create an AB record.

I appreciate any help.

Thanks,

Roger
