sults to user queries while looking at the relevant data items only once and in a ﬁxed order (determined by the stream-arrival pattern). Two key parameters for query processing over continuous data-streams are (1) the amount of memory made available to the on-line algorithm, and (2) the per-item processing timerequired by the query processor.

Hash Aggregate
20.09.2006· The residual predicate from the hash aggregate is used to compare rows in the hash table to input rows in case we have a hash value collision. Notice also that with the hash aggregate we do not need a sort. A sort requires more memory than the hash aggregate since we must sort 1000 rows but only need memory in the hash aggregate …
