Interface DatasetBuilder<K,V>

Type Parameters:

K - Type of a key in upstream data.

V - Type of a value in upstream data.

All Known Implementing Classes:

CacheBasedDatasetBuilder, LocalDatasetBuilder

public interface DatasetBuilder<K,V>

A builder constructing instances of a Dataset. Implementations of this interface encapsulate logic of building specific datasets such as allocation required data structures and initialization of context part of partitions.
