> It would be good if Avro would permit one to still read data if a type or
> field name has been changed. I propose we add a notion of name _aliases_.
> Aliases could be listed for every named type and for record fields. The
> writers schema would be permitted to contain any of the aliases.
> In general, this permits one to construct schemas that can read different
> types into a single type. One could use this not just to handle renamings,
> but also to join different datasets. For example, if two datasets each
> contain differently named records with a date and an ip address field, this
> could be used be used to project these both to a single record with just
> those fields.
