Class SparseLocalOffHeapVector

java.lang.Object

org.apache.ignite.ml.math.impls.vector.AbstractVector

org.apache.ignite.ml.math.impls.vector.SparseLocalOffHeapVector

All Implemented Interfaces:

Externalizable, Serializable, Destroyable, MetaAttributes, StorageOpsMetrics, Vector

public class SparseLocalOffHeapVector
extends AbstractVector

Implementation for Vector assuming sparse logic and local offheap JVM storage. It is suitable for data sets where local, non-distributed execution is satisfactory and on-heap JVM storage is not enough to keep the entire data set.
