CAPE : Engine for Querying and Monitoring Streaming Data static data Standing queries data Query data one-time queries streams of data Example of Stream Data Applications: • Market Analysis –Streams of Stock Exchange Data get rich • Critical Care –Streams of Vital Sign Measurements – save lives • Physical Plant Monitoring –Streams of Environmental Readings – protect env

Stream Query Monitoring Projects � CAPE Query Engine Load Spiller Service (JAVA): � Service for run-time spill/unspill services for a complete query plan � Design query policies, operator data structures, algorithms � Implement in CAPE engine, conduct experiments � Event Pattern Monitoring Engine � Support Sequence Queries and Extend to more Complex AND/OR Patterns � Handle out-of-order event input arrivals by either logging and result-correction or by exploiting predicting meta-data messages � Scale to support multiple event queries � RFID Data Service � Install actual RFID equipment in some campus environment � Support simple data collection and tracking queries, of either goods or people � Handling missing values or clean-up errors using domain knowledge � Visual Stream Monitoring Tool � Target a real stream application, such as flow simulation tool � Develop algorithms for multi-resolution data aggregation in time and space � Support visual query refinement of asking about a particular object or region

• PC-Cluster Java Applications � Acquisition: Brand New Purchase of 20 -Node High-Performance PC Cluster (Rundensteiner/Mani/Heineman – NSF ) �Project 1: Implement and evaluate allocation/reallocation algorithms for assigning stream query nodes to processor � Project 2: Implement and compare two solutions for migrating at run-time query plans into new rewritten plans � Project 3: Develop launch-pad for statistics monitoring for monitoring DCAPE experiments
