Subject [jira] [Commented] (AVRO-1402) Support for DECIMAL type
Date Thu, 10 Apr 2014 20:36:15 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13965808#comment-13965808

Skye Wanderman-Milne commented on AVRO-1402:
--------------------------------------------

This looks great Tom! If I understand correctly, this also allows for a single logical type
to have multiple possible encodings; for example, we could someday add an alternate decimal
encoding that is backed by "fixed" rather than "bytes". One question: what do you mean by
"Language implementations may choose to represent logical types with an appropriate native
type, although this is not required"? Is this referring to logical types not explicitly defined
in the spec?

> 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).
