Philip Zeyliger commented on AVRO-600:
--------------------------------------
This seems like it adds quite a bit of complexity to the base Avro system.
Could this be layered on top? Perhaps, a separate way to indicate a
transformation from one schema to another, which could then be used at
read-time?

> Issue Type: New Feature
> Components: java, spec
> Reporter: Doug Cutting

> 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.
