Data stream management systems (DSMSs) receive large overheads when queries directly access the serial non-indexed incoming stream. Our novel architecture, presented in this work, addresses this problem by indexing the incoming dataflow based on a specially designed data structure. The role of this data structure is as fundamental for our DSMS as the role of a relation in a relational DBMS. The architecture achieves reusability, query parallelism and O(1) constant time complexity access to streamed data. The system managed to run the maximum level of difficulty the linear road benchmark has (10 expressways), demonstrating excellent performance results.
