Xuefu Zhang commented on AVRO-1402:
-----------------------------------
Thanks for the clarification, [~rdblue]. That makes sense.
Speaking of enforcement, I am curious about how much Avro is able to validate
against the spec. For instance, the latest spec requires bigendian for
encoding, but decimal data given to Avro to store by the application is in
terms of bytes, and I assume that Avro isn't able to find out the endianness.
Other area of rules, such as scale should be less than or equal to precision,
or scale should be positive, isn't present in the spec. I guess the bigger
question is whether or what validation will be enforced by Avro.Or it's
completely up to the application, and the spec is more of a guideline.

> Currently, Avro does not seem to support a DECIMAL type or equivalent.
> http://avro.apache.org/docs/1.7.5/spec.html#schema_primitive
> Adding DECIMAL support would be particularly interesting when converting
> types from Avro to Hive, since DECIMAL is already a supported data type in
> Hive (0.11.0).
