摘要:
Provided are a system and method for processing continuous integrated queries on both data stream and stored data using user-defined shared trigger. The system includes a data stream manager for managing data stream inputted from outside; a continuous integrated queries manager for managing the continuous integrated queries inputted from an external application; a trigger manager for managing the user-defined shared trigger inputted from the external application and registering the user-defined shared trigger in an external database; a trigger result manager for forming and managing a trigger result set from a performance result of the user-defined shared trigger registered in the cooperation database; and a continuous integrated queries performer for processing the continuous integrated queries referring to the transmitted data stream and trigger result set.

Provided are a system and a method for processing integrated queries against an input data stream and data stored in a database using trigger. The system for processing an integrated query against an input data stream and data stored in a database using a trigger, including: a data stream manager for managing a continuously inputted data stream; a trigger result manager for registering a trigger in a database which interworks with the trigger result manager and forming a set of results that are obtained by executing the registered trigger to thereby provide the set of results in real time; and an executer for processing an integrated query against the data stream from the data stream manager and data stored in the database, wherein the integrated query is processed by referring to the set of results from the trigger result manager for the data stored in the database.

Disclosed herein are an apparatus and method for managing a data stream distributed parallel processing service. The apparatus includes a service management unit, a Quality of Service (QoS) monitoring unit, and a scheduling unit. The service management unit registers a plurality of tasks constituting the data stream distributed parallel processing service. The QoS monitoring unit gathers information about the load of the plurality of tasks and information about the load of a plurality of nodes constituting a cluster which provides the data stream distributed parallel processing service. The scheduling unit arranges the plurality of tasks by distributing the plurality of tasks among the plurality of nodes based on the information about the load of the plurality of tasks and the information about the load of the plurality of nodes.
