Doug Cutting commented on AVRO-95:
----------------------------------
> it's a bit icky that changes to the list passed in effect the writing.
I agree, but that's a more systemic problem. None of Schema's constructors
copy data passed in. The current style is leave that to applications -- folks
shouldn't generally modify data after passing it to a Schema constructor.
Changing that may have performance implications, and should be done thoroughly
rather than piecemeal. But adding to a union is generally harmless.
I'll commit this as-is unless there are objections.

> My use case is that I have a bunch of different kind of events (in a
> hierarchy actually, which right now isn't supported either, see AVRO-93),
> that I would like to write out to log files using Avro. Unfortunately,
> writing more than one type via reflection seems to be broken currently. I
> think I can tell from the code and the resulting data file that this should
> be supported, but it seems that there are a few issues with the
> implementation right now.
