Interface Summary |
| Aggregator<T> |
Aggregate a sequence of values into a possibly smaller sequence of the same type. |
| CombineFn.Aggregator<T> |
Deprecated. Use Aggregator |
| CombineFn.AggregatorFactory<T> |
Deprecated. Use PGroupedTable.combineValues(Aggregator) which doesn't require a factory. |
| Emitter<T> |
Interface for writing outputs from a DoFn. |
| PCollection<S> |
A representation of an immutable, distributed collection of elements that is
the fundamental target of computations in Crunch. |
| PGroupedTable<K,V> |
The Crunch representation of a grouped PTable, which corresponds to the output of
the shuffle phase of a MapReduce job. |
| Pipeline |
Manages the state of a pipeline execution. |
| PipelineExecution |
A handle to allow clients to control a Crunch pipeline as it runs. |
| PObject<T> |
A PObject represents a singleton object value that results from a distributed
computation. |
| PTable<K,V> |
A sub-interface of PCollection that represents an immutable,
distributed multi-map of keys and values. |
| Source<T> |
A Source represents an input data set that is an input to one or more
MapReduce jobs. |
| SourceTarget<T> |
An interface for classes that implement both the Source and the
Target interfaces. |
| TableSource<K,V> |
The interface Source implementations that return a PTable. |
| TableSourceTarget<K,V> |
An interface for classes that implement both the TableSource and the
Target interfaces. |
| Target |
A Target represents the output destination of a Crunch PCollection
in the context of a Crunch job. |
| Tuple |
A fixed-size collection of Objects, used in Crunch for representing joins
between PCollections. |
