Subject [jira] [Commented] (BEAM-221) ProtoIO
Date Sat, 25 Jun 2016 04:17:16 GMT

    [ https://issues.apache.org/jira/browse/BEAM-221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15349050#comment-15349050
] 

Daniel Halperin commented on BEAM-221:
--------------------------------------

One idea was to simply wrap AvroIO in a Composite PTransform:
* Avro schema is just a single byte[].
* On read, convert from byte[] to the user's proto.
* On write, convert from proto to byte[].

In this way, ProtoIO would just be a simple wrapper for AvroIO.Read+ParDo (read) or ParDo+AvroIO.Write.

> Make it easy to read and write binary files of Protobuf objects. If there is a standard
open source format for this, use it.
> If not, roll our own and implement it?
