Till Rohrmann commented on FLINK-1873:
--------------------------------------

I think it's good to use Flink's matrix and vector representations as long as 
you don't have to perform operations. For that you can convert Flink's 
primitives into Breeze's primitives. The conversion should almost come for 
free, because Flink uses the same underlying representation of dense and sparse 
matrices/vectors as Breeze.

> It would help to implement machine learning algorithm more quickly and 
> concise if Flink would provide support for storing data and computation in 
> distributed matrix. The design of the implementation is attached.
