That said, just for a comparison purpose, spark has its own model export
and import feature, along with pmml export. Hoping to fully support pmml import

I agree with @sachingoel0101 on the import complexity but, from our point
of view, Flink is the perfect platform to evaluate models in streaming and we
are using it

As the original author of this PR, I'd say this:
I tried implementing the import features but they aren't worth it. You have
to discard most of the valid

@sachingoel0101 I agree. Nonetheless, an easy way to store and move a model
generated in batch to a streaming enviroment would be a really useful feature
and we go back

That is a good point. In streaming setting, it does indeed make sense for
the model to be available. However, in my opinion, then it would make sense to
actually

I'm all for that. Flink's models should be transferable at least across
flink. But that should be part of a separate PR, and not block this one as it
has been

Well that wouldn't be a problem for the export: you will create and
therefore export only models that have `double` as datatype for parameters but
that's not an issue.

Hello,
any news on this PR?
@smarthi PMML is actually an industry standard and widely used to support
model portability in complex infrastructures.

Hi @chobeat, thanks for leaving your comments.
About compatibility with other system (such as R or MLlib), I meant that we
cannot achieve compatibility with

Hi @chobeat, thanks for pinging this issue. I forgot sending a discuss

Hi @chiwanpark,

portability in FlinkML?
I've used PMML extensively in a previous

Suggest that you see how PMML been's done on Oryx 2.0 (PMML in Spark
followed Oryx 2.0). PMML support was discussed various times on the Mahout
project and was never

The PMML model is quite extensive, and there isn't enough support in the ML
library for utilizing most of the things [like FieldUsageType, DataTypes etc.].
