Ryan Blue commented on AVRO-1402:
---------------------------------
bq. A logical type is always encoded in exactly the same way as the equivalent
Avro type.
Could we reword this to "A logical type is always serialized using its
underlying Avro type." I'd like to avoid confusion because some logical types
(like decimal) specify the "encoding" that determines how to convert between
the object representation and the underlying Avro type.
Last, I think that we should add that fixed may also be annotated with a
decimal logical type, but I don't want to hold up this issue if people disagree
-- in that case we should discuss adding it in a separate issue/commit.

> 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).
