Methods in org.apache.hudi.common.data that return HoodiePairData

Modifier and Type	Method and Description
<K,V> HoodiePairData<K,V>	HoodieData.flatMapToPair(SerializableFunction<T,Iterator<? extends Pair<K,V>>> func) Maps every element in the collection into a collection of the Pairs of new elements using provided mapping func, subsequently flattening the result (by concatenating) into a single collection NOTE: That this operation will convert container from HoodieData to HoodiePairData This is an intermediate operation
<K,V> HoodiePairData<K,V>	HoodieListData.flatMapToPair(SerializableFunction<T,Iterator<? extends Pair<K,V>>> func)
<W> HoodiePairData<K,W>	HoodieListPairData.flatMapValues(SerializableFunction<V,Iterator<W>> func)
HoodiePairData<K,Iterable<V>>	HoodieListPairData.groupByKey()
HoodiePairData<K,Iterable<V>>	HoodiePairData.groupByKey() Groups the values for each key in the dataset into a single sequence
<W> HoodiePairData<K,Pair<V,Option<W>>>	HoodieListPairData.leftOuterJoin(HoodiePairData<K,W> other)
<W> HoodiePairData<K,Pair<V,Option<W>>>	HoodiePairData.leftOuterJoin(HoodiePairData<K,W> other) Performs a left outer join of this dataset against other.
<L,W> HoodiePairData<L,W>	HoodieListPairData.mapToPair(SerializablePairFunction<Pair<K,V>,L,W> mapToPairFunc)
<L,W> HoodiePairData<L,W>	HoodiePairData.mapToPair(SerializablePairFunction<Pair<K,V>,L,W> mapToPairFunc)
<K,V> HoodiePairData<K,V>	HoodieData.mapToPair(SerializablePairFunction<T,K,V> func) Maps every element in the collection using provided mapping func into a Pair of elements K and V
<K,V> HoodiePairData<K,V>	HoodieListData.mapToPair(SerializablePairFunction<T,K,V> func)
<W> HoodiePairData<K,W>	HoodieListPairData.mapValues(SerializableFunction<V,W> func)
<W> HoodiePairData<K,W>	HoodiePairData.mapValues(SerializableFunction<V,W> func) Maps values of this HoodiePairData container leveraging provided mapper
HoodiePairData<K,V>	HoodieListPairData.reduceByKey(SerializableBiFunction<V,V,V> combiner, int parallelism)
HoodiePairData<K,V>	HoodiePairData.reduceByKey(SerializableBiFunction<V,V,V> combiner, int parallelism) Reduces original sequence by de-duplicating the pairs w/ the same key, using provided binary operator combiner.
