UnfinishedJoinOperation

class UnfinishedJoinOperation[L, R] extends UnfinishedJoinOperationBase[L, R, JoinDataSet[L, R]]

An unfinished inner join operation that results from calling DataSet.join(). The keys for the left and right side must be specified using first where and then equalTo.

For example:

val left = ...
val right = ...
val joinResult = left.join(right).where(...).equalTo(...)
L

The type of the left input of the join.

R

The type of the right input of the join.

  24. def where[K](fun: (L) ⇒ K)(implicit arg0: TypeInformation[K]): HalfUnfinishedKeyPairOperation[L, R, JoinDataSet[L, R]]

    Specify the key selector function for the left side of the key based operation.

    Specify the key selector function for the left side of the key based operation. This returns a HalfUnfinishedKeyPairOperation on which equalTo must be called to specify the key for the right side. The result after specifying the right side key is the finished operation.

    Specify the key fields for the left side of the key based operation. This returns a HalfUnfinishedKeyPairOperation on which equalTo must be called to specify the key for the right side. The result after specifying the right side key is the finished operation.

    This only works on Tuple DataSet.
