Achieving High Freshness and Optimal Throughput in CPU-Limited Execution of Multi-join Continuous Queries
[chapter]
2011
Lecture Notes in Computer Science
Due to high data volumes and unpredictable arrival rates, continuous query systems processing expensive queries in real-time may fail to keep up with the input data streams -resulting in buffer overflow and uncontrolled data loss. We explore join direction adaptation (JDA) to tackle CPU-limited processing of multijoin stream queries. The existing JDA solutions allocate the scarce CPU resources to the most productive half-way join within a single operator. We instead leverage the operator
