Jeremy Kahn commented on AVRO-1318:
-----------------------------------
It is not an end-user use case. it's a useful performance win, if you're
caching encoder and decoder objects, as Uri's changes do. I've written my own
extensions based heavily on this "signature" behavior.
I'd be happy to have [~laserson]'s perf branch added. [~cutting], perhaps you
can go chat with him about this? He's a Clouderian, if I understand correctly.

> Python schema objects need to produce a simple representation that
> demonstrates their field identity. {avro.schema.Schema} objects need to
> provide a {fingerprint} member field to enable quick checking of schema
> matching (even when the schema has other, possibly changed decoration).
> Based on a patch pulled from [~laserson]'s proposed changes to make a
> collection of C-typing hints. These changes will be backwards-compatible.
