CheckpointedDrm

trait CheckpointedDrm[K] extends DrmLike[K]

Checkpointed DRM API. This is a matrix that has optimized RDD lineage behind it and can be therefore collected or saved.

K

matrix key type (e.g. the keys of sequence files once persisted)

    Action operator -- does not necessary means Spark action; but does mean running BLAS optimizer and writing down Spark graph lineage since last checkpointed DRM.
