    Abstract: The following description relates to a method and an apparatus for merging distributed stream processing services. A method for merging distributed stream processing services according to an example includes generating a global service tree based on one distributed stream processing service; when a new distributed stream processing service different from the one distributed stream processing service is inputted, generating an individual service tree for the new distributed stream processing service; and updating the global service tree by merging at least one node commonly existing in both the global service tree and the individual service tree. Common resources may be allocated to tasks (or instances) existing commonly in distributed stream processing services.

    Abstract: An apparatus and method for managing stream processing tasks are disclosed. The apparatus includes a task management unit and a task execution unit. The task management unit controls and manages the execution of assigned tasks. The task execution unit executes the tasks in response to a request from the task management unit, collects a memory load state and task execution frequency characteristics based on the execution of the tasks, detects low-frequency tasks based on the execution frequency characteristics if it is determined that a shortage of memory has occurred based on the memory load state, assigns rearrangement priorities to the low-frequency tasks, and rearranges the tasks based on the assigned rearrangement priorities.
