An AbstractStreamingJoinOperator.OuterRecord is a composite of record and numOfAssociations. The numOfAssociations represents the number of associated records in the other side. It is used when the record is from outer side (e.g. left side in LEFT OUTER JOIN). When the numOfAssociations is ZERO, we need to send a null padding row. This is useful to avoid recompute the associated numbers every time.

When the record is from inner side (e.g. right side in LEFT OUTER JOIN), the numOfAssociations will always be -1.
