In an attempt to reduce the resulting memory and execution time overhead, a general method was recently proposed, consisting in “masking” all the intermediate data. This masking strategy is possibl...

The window-based stream join is an important operator in all data streaming systems. It has often high resource requirements so that many efficient sequential as well as parallel versions of it were proposed in the literature. The parallel stream join operators recently gain increasing interest because hardware is getting more and more parallel. Most of these operators, however, are only optimi...
