----------------------------------------
Summary: Native support for kryo serialization of tensor types.
Key: MAHOUT-1732
URL: https://issues.apache.org/jira/browse/MAHOUT-1732
Project: Mahout
Issue Type: Improvement
Reporter: Dmitriy Lyubimov
Assignee: Dmitriy Lyubimov
Fix For: 0.10.2
Right now, the serialization of tensor types (matrix, vector) is double-bridged
thru VectorWritable and MatrixWritable.
a new writeup of kryo serializers in this issue provides direct support for
serializing vector and matrix types (also accounting for their structural
flavors).
This is a first rewrite, so improvements probably could be provided, but i so
far have not found this to become a visible bottleneck again over other spark
io costs.
