naturally main-memory-based. This makes main memory the bottleneck for
scalability. This doctoral thesis addresses this problem and presents
a toolkit for effective buffer management in main-memory-based
stream processors. We have confirmed the efficacy of our techniques by
extensive experiments and by publication at international venues.
To compare our contributions to related work in a systematic manner,
we contribute an abstract framework for XML stream processing. This
framework allows us to gain a greater-picture view over the factors
influencing the main memory consumption.
