UnfinishedJoinOperation

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.

def where[K](fun: KeySelector[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.
