Robert Metzger commented on FLINK-1388:
---------------------------------------
Cool.
Some feedback:
- I think an integration with {{DataSet.internalWriteAsCsv()}} would be nice.
- From there, you can also pass the TypeInformation into the method (right now,
the code is doing the TypeExtraction on every tuple. That won't work on large
data sets)
- I think it would be much easier for you to extend from the
{{FileOutputFormat}}. It will do all the file-related stuff for you (your code
does not allow to write files to HDFS).
