Data Stream Warehousing In Tidalrace

Theodore Johnson, Vladislav Shkapenyuk
2015 Conference on Innovative Data Systems Research  
In this paper we describe the Tidalrace system, our motivations for developing it, and architectural features of Tidalrace that support data stream warehousing.  ...  The partitions in a partition set are joined in one unit of processing. If the join has partition sets (PS1, … PSj), the result of the join is the union of the individual partition set joins.  ...  Partition-wise Optimization As we have discussed, joins in a data stream warehouse are almost always band joins on the table's timestamp.  ...

Network-Aware Workload Scheduling for Scalable Linked Data Stream Processing

Lorenz Fischer, Thomas Scharrenbach, Abraham Bernstein
2013 International Semantic Web Conference  
Acknowledgements We would like to thank Thomas Hunziker, who wrote the first prototype of the KATTS system during his master's thesis in our group.  ...  The Suitability of Graph Partitioning for Scheduling The critical element for optimizing the scheduling using graph partitioning is that the operators can be parallelized with an adequate data partitioning  ...  Once this task has been achieved, which we got due to the pre-partitioned datasets, all computation can be managed on a local machine, as no further joins are necessary.  ...
