Abstract
A system for a data stream management system includes a filter transport aggregate for a high speed input data stream with a plurality of packets each packet comprising attributes. The system includes an evaluation system to evaluate the high speed input data stream and partitions the packets into groups the attributes and a table, wherein the table stores the attributes of each packets using a hash function. A phantom query is used to define partitioned groups of packets using attributes other than those used to group the packets for solving user queries without performing the user queries on the high speed input data stream.
