[jira] Commented: (AVRO-638) make reflect, specific and generic data compatible

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-638?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975926#action_12975926 ] 

Doug Cutting commented on AVRO-638:
-----------------------------------

With AVRO-669 committed, reflect data is now a superset of specific, and specific is a superset of generic.  The only potential source of incompatibility is that ReflectDatumReader always creates java.lang.String for string data, while SpecificDatumReader and GenericDatumReader always create org.apache.avro.util.Utf8.

Unless there are objections, I will close this as fixed.

> With AVRO-605 and AVRO-86, reflect, specific and generic are nearly compatible.  Records, primitive types, maps and enums now share common representations.  AVRO-637 would add arrays.  After that I think only some issues with union type dispatch would remain.  Then specific and/or generic data could be arbitrarily intermixed with reflect data with ReflectDatumReader and ReflectDatumWriter.
