RJ Nowling commented on SPARK-2308:

That sounds like a good idea for a test.  I'll report back.

>            Priority: Minor
> Mini-batch is a version of KMeans that uses a randomly-sampled subset of the data points
in each iteration instead of the full set of data points, improving performance (and in some
cases, accuracy).  The mini-batch version is compatible with the KMeans|| initialization algorithm
currently implemented in MLlib.
> I suggest adding KMeans Mini-batch as an alternative.
> I'd like this to be assigned to me.
