Multiple fields referring to the same message

[debackerl]

Hi,

Is it possible to references a single message from multiple fields?
Let's suppose that we want to transfer all billing of a company, the
'bill' message would contain a 'customer' field. However, multiple
bills will have the same customer, will the customer be shared
automatically (i.e. only transferred once) or do I have to use unique
IDs instead?

You will have to design ids on a higher level instead -- foreign keys
etc. are beyond the scope of protocol buffers.

Sorry, you'll need to use IDs or indexes of some sort, as Protocol Buffers are trees, not graphs.
