Title:
METHOD AND SYSTEM FOR CONTINUOUS QUERY PROCESSING
Document Type and Number:
WIPO Patent Application WO/2013/144536
Kind Code:
A3
Abstract:
The invention relates to a method and system that provide a continuous querying mechanism that analyses real-time data streams to generate relevant results. It leverages data grid and event processing technology to provide a high performance and extremely scalable continuous querying solution. An embodiment of the invention provides a flexible querying language and data storage to allow users to register their interest in specific types of data, e.g. processes. The users are notified of matching results using an event-based mechanism. In order to efficiently analyse a large amount of data, the embodiment uses a grid infrastructure that allows storage of the data across many grid nodes and distributes the query execution workload, avoiding the bottleneck represented by constantly querying a database. Continuous queries are stored in a Continuous Query Registry and that Registry is invoked every time an insert or update event occurs on the triple store. In the case where a triple matches one or more of the patterns defined in the registry, the triple invokes a matching and binding process that generates new query models by binding variables and atoms to values in the incoming triple. The generated query models are then executed across the grid and any results are notified to the observer.
