> We use our Thrift types in Hadoop map/reduce, sometimes as keys. As such,
> they need to be compared to other keys to be sorted. Right now, the only way
> to compare two Thrift objects is to serialize them and do byte comparison.
> It'd be nice if we could compare two objects directly.
> The implementation of such a compareTo would look a lot like the equals()
> implementation already present, and delegate to the subtypes' compareTo
> methods appropriately. The ordering of the field declarations in the .thrift
> file would indicate the sort order between fields. In some situations this
> would make the sorting somewhat arbitrary, but it would be stable, and if you
> really needed the sorting to take into account fields in a specific order,
> you could order your fields appropriately.
