{"type": "int"}, {"type": "string"} is not valid json, so you definitely can't 
do that. But

[{"type": "int"}, {"type": "string"}] is a valid schema -- it can encode a 
single value that is either an int or a string. At the highest level, your 
schema can only be one type, but that type may be (and in fact probably will 
be) a complex type -- a union of records or a single record.

Does that answer your question?

one of the 3 that it listed.


In short, can I do this as a single schema?

{type : int},

{type : string},

{type : int},


Or do the following as a single schema?

{type : int},

{type : record },

{type : record }, // Not the same as the previous.

{type : string},


Or do I have to "embed" the above under a complex type like a record if I want 
complex schema? Or does "one of" mean I have to choose one and exactly one for 
the high top-most level of the schema?


Thanks!!

In Avro IDL, how can I import an externally provided schema?

[Bob Price]

I asked an Avro IDL question in StackOverflow but got no responses. Can anyone 
here answer it?
It is at: In Avro IDL, how can I import an externally provided schema?

A simple example illustrates my problem. In essence, I am working on a large 
project that has code split across...
