MANAGING STREAM COMPONENTS BASED ON VIRTUAL MACHINE PERFORMANCE ADJUSTMENTS

摘要

Embodiments of the disclosure include a method, a system, and a computer program product for modifying a stream operator based on the virtual resources. The method includes receiving a first resource allocation and a second resource allocation of a virtual resource for a virtual machine supporting a stream computing application. The method also includes determining whether the second resource allocation changed within a tolerance relative to the first resource allocation. The method also includes identifying a stream operator in the stream computing application using the virtual resource of the virtual machine. The method also includes modifying the stream operator to accommodate the second resource allocation in response to the second resource allocation changing relative to the first resource allocation.

1. A method comprising:
receiving a first resource allocation and a second resource allocation of a virtual resource for a virtual machine supporting a stream computing application; determining whether the second resource allocation changed within a tolerance relative to the first resource allocation; identifying a stream operator in the stream computing application using the virtual resource of the virtual machine; modifying the stream operator to accommodate the second resource allocation in response to the second resource allocation changing relative to the first resource allocation.
