Subject [jira] [Commented] (FLINK-1388) POJO support for writeAsCsv
Date Wed, 18 Feb 2015 14:57:11 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1388?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14325974#comment-14325974
] 

Robert Metzger commented on FLINK-1388:
---------------------------------------

- The {{DataSet.internalWriteAsCsv}} currently checks if the DataSet type is a Tuple. I would
extend the functionality to also allow POJOs there. 
- {{TypeExtractor.createTypeInfo()}} is meant to be called only when the job is being created
on the client side ("pre flight" phase).
