[jira] [Commented] (AVRO-1105) Scala API for Avro

["Scott Carey (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AVRO-1105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13534590#comment-13534590 ] 

Scott Carey commented on AVRO-1105:
-----------------------------------

I did a little bit of research on Scala macros.  As of Scala 2.10 (nearing release), macros cannot create named types or methods, but they can implement or override methods defined in the source or create anonymous types.
Until there are type macros they cannot be used to fully replace code generation.  However, they can be used to optimize / implement an API defined in advance, such as the "Dynamic" use cases.  They also do not yet interact with annotations deeply, which would be very useful for some "Code first" use cases -- think the equivalent of Java reflection on annotations at compile time rather than runtime, so that a macro can be triggered to generate code declaratively by the presence of an annotation.
