             Summary: Preregister ML types for Kryo serialization
                 Key: FLINK-2053
                 URL: https://issues.apache.org/jira/browse/FLINK-2053
             Project: Flink
          Issue Type: Improvement
          Components: Machine Learning Library
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 0.9


Currently, FlinkML uses interfaces and abstract types to implement generic algorithms. As
a consequence we have to use Kryo to serialize the effective subtypes. In order to speed the
data transfer up, it's necessary to preregister these types in order to assign them fixed
IDs.
