Adaptive optimization of join trees for multi-join queries over sensor streams
Data processing applications for sensor streams have to deal with multiple continuous data streams with inputs arriving at highly variable and unpredictable rates from various sources. These applications perform various operations (e.g. filter, aggregate, join etc) on incoming data streams in real-time according to predefined queries or rules. Since the data rate and data distribution fluctuate...
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 کاملOptimization of Multi-Way Join Queries for Parallel Execution
Most of the existing relational database query optimizers generate multi-way join plans only from those linear ones to reduce the optimization overhead. For multiprocessor computer systems, this strategy seems inadequate since it may reduce the search space too much to generate near-optimal plans. In this paper we present a framework for optimization of multiway join queries in multiprocessor c...
متن کاملOptimization of Parallel Execution for Multi-Join Queries
In this paper, we study the subject of exploiting inter-operator parallelism to optimize the execution of multi-join queries. Speciically, we focus on two major issues: (i) scheduling the execution sequence of multiple joins within a query, and (ii) determining the number of processors to be allocated for the execution of each join operation obtained in (i). For the rst issue, we propose and ev...
متن کاملOptimizing Multi-Join Stream Queries for Sensor Networks
Sensors are becoming ubiquitous, and increasingly integrated with out lives. Sensor networks are being used in a wide range of applications in fields such as military, medical, process control and manufacturing, bio-terrorism, house automation etc. In these applications streams of data that flow out of the sensors are processed, analyzed and managed. However due to the dynamic and continuous na...
