Multiple Continuous Queries Evaluation over Data Streams
Query processing for data streams should be continuous and rapid, which requires strict time constraint. In most previous researches, in order to guarantee this constraint, the evaluation order of join predicates in a continuous query is optimized by a greedy. However, the greedy strategy traces only the first promising plan, so that it often finds a sub-optimal plan. This paper proposes an imp...
متن کاملA Temporal Foundation for Continuous Queries over Data Streams
Despite the surge of research in continuous stream processing, there is still a semantical gap. In many cases, continuous queries are formulated in an enriched SQL-like query language without specifying the semantics of such a query precisely enough. To overcome this problem, we present a sound and precisely defined temporal operator algebra over data streams ensuring deterministic query result...
متن کاملTransformation of Continuous Aggregation Join Queries over Data Streams
We address continuously processing an aggregation join query over data streams. Queries of this type involve both join and aggregation operations, with windows specified on join input streams. To our knowledge, the existing researches address join query optimization and aggregation query optimization as separate problems. Our observation, however, is that by putting them within the same scope o...

متن کاملQueueing Analysis of SPJ Queries over Continuous Data Streams
Currently, considerable body of work exists on stream data processing. Research on data streams varies from algorithms for computing various operators on streams to the design of architectures and implementation of systems for large scale stream processing. Most of the work has focused on the use of queues with traditional query processing operators to handle unpredictable, real-time processing...
