Constructor Detail

ReduceTLink

public ReduceTLink(BatchEnvironment tSetEnv,
                   ReduceFunc<T> rFn,
                   int sourceParallelism,
                   Schema schema)

Method Detail

setName

public ReduceTLink<T> setName(java.lang.String name)

Description copied from interface: TLink

Name of the TSet and return the same tlink

Parameters:

name - name

Returns:

this tlink

getEdge

public Edge getEdge()

lazyCache

public CachedTSet<T> lazyCache()

Description copied from interface: StoringData

Performs caching lazily. i.e. cache operation would only be performed when the TSet is evaluated explicitly.

Specified by:

lazyCache in interface StoringData<T>

Overrides:

lazyCache in class BatchSingleLink<T>

Returns:

Cached TSet

cache

public CachedTSet<T> cache()

Description copied from interface: StoringData

Runs this TSet and caches the data to an in-memory DataPartition and exposes the data as another TSet.

Specified by:

cache in interface StoringData<T>

Overrides:

cache in class BatchSingleLink<T>

Returns:

Cached TSet

lazyPersist

public PersistedTSet<T> lazyPersist()

Description copied from interface: StoringData

Performs persisting lazily.

Specified by:

lazyPersist in interface StoringData<T>

Overrides:

lazyPersist in class BatchSingleLink<T>

Returns:

Persisted / Checkpointed TSets

persist

public PersistedTSet<T> persist()

Description copied from interface: StoringData

Similar to cache, but the data is stored in a disk based DataPartition. This method would also expose the checkpointing ability to TSets.

Specified by:

persist in interface StoringData<T>

Overrides:

persist in class BatchSingleLink<T>

Returns:

Persisted / Checkpointed TSets
