-------------------------------------
Doug, finally I have created a feature branch with this based on the latest
trunk:
https://github.com/zolyfarkas/avro/tree/trunk-AVRO-1723
Please review, the patch also contains:AVRO-1667 without it the unit test to
test the functionality will break.
Let me know if you have any comments.
> Add support for forward declarations in avro IDL
> ------------------------------------------------
>
> Key: AVRO-1723
> URL: https://issues.apache.org/jira/browse/AVRO-1723
> Project: Avro
> Issue Type: Improvement
> Affects Versions: 1.8.0
> Reporter: Zoltan Farkas
>
> Currently Recursive data structures like:
> record SampleNode {
> int count = 0;
> array<SamplePair> samples = [];
> }
> record SamplePair {
> string name;
> SampleNode node;
> }
> It is not possible to declare in IDL,
> however it is possible to declare in avsc (with fix from
> https://issues.apache.org/jira/browse/AVRO-1667 )
> It is actually not complicated to implement, here is some detail on a
> possible implementation:
> https://github.com/zolyfarkas/avro/commit/210c50105717149f3daa39b8d4160b8548b8e363
> This would close a capability gap with google protocol buffers...
