Aljoscha Krettek updated FLINK-11096:
-------------------------------------
Component/s: (was: Table SQL / API)
> Create a new table based flink ML package
> -----------------------------------------
>
> Key: FLINK-11096
> URL: https://issues.apache.org/jira/browse/FLINK-11096
> Project: Flink
> Issue Type: Sub-task
> Components: Library / Machine Learning
> Reporter: Weihua Jiang
> Priority: Major
>
> Currently, the DataSet based ML library is under org.apache._flink.ml_ scala
> package and under _flink-libraries/flink-ml directory._
>
> There are two questions related to packaging:
> # Shall we create a new scala/java package, e.g. org.apache.flink.table.ml?
> Or still stay in org.apache.flink.ml?
> # Shall we still put new code in flink-libraries/flink-ml directory or
> create a new one, e.g. flink-libraries/flink-table-ml and corresponding maven
> package?
>
> I implemented a prototype for the design and found that the new design is
> very hard to fit into existing flink.ml codebase. The existing flink.ml code
> is tightly coupled with DataSet API. Thus, I have to rewrite almost all parts
> of flink.ml to get some sample case to work. The only reusable code from
> flink.ml are the base math classes under _org.apache.flink.ml.math_ and
> _org.apache.flink.ml.metrics.distance_ packages.
> Considering this fact, I will prefer to create a new package
> org.apache.flink.table.ml and a new maven package flink-table-ml.
>
> Please feel free to give your feedbacks.
