Sam Pullara commented on AVRO-1006:
-----------------------------------

This would be great. I ended up using the text representation + SHA256 in 
Avrobase for my schema keys. I would love to see a standard way that worked 
across languages and no matter how mangled the schema JSON was rendered. On the 
0.001% collision rate, that seems high to me - would a 128-bit hash be a better 
choice?
