Hi @chobeat, thanks for pinging this issue. I forgot sending a discuss
email to mailing thread. I think we have to discuss about followings:
* What is main purpose to support PMML? Is this feature for only model
portability in FlinkML? If not, we have to support other systems such as R or
Spark MLlib.
* What about FlinkML only format? I think that support for distributed
system in PMML is poor. XML-based format is hard to parallelize.
I would like to create a general ML model importing/exporting framework.
Then, we can easily add the PMML support based on the framework.
