US 2016/0103697 A1 · TEARING DOWN VIRTUAL MACHINES IMPLEMENTING PARALLEL OPERATORS IN A STREAMING APPLICATION BASED ON PERFORMANCE

Abstract

A streams manager monitors performance of parallel portions of a streaming application implemented in multiple virtual machines (VMs). When the performance provided by the multiple VMs is no longer needed, one or more of the VMs can be torn down. The performance of the VMs is monitored. When the least performing VM can be torn down, it is torn down. When the least performing VM cannot be torn down, information regarding a better performing VM is gathered, and it is determined whether the least performing VM can be made more similar to the better performing VM. When the least performing VM can be made more similar to the better performing VM, the least performing VM is changed to improve its performance, and the better performing VM is torn down.

A computer-implemented method executed by at least one processor for managing a streaming application, the method comprising:

executing a streaming application that comprises a flow graph that includes a plurality of operators that process a plurality of data tuples, wherein the flow graph comprises a first set of operators implemented in a first virtual machine and a second set of operators implemented in a second virtual machine, wherein the first set of operators and the second set of operators include similar operators and connections between operators and operate on data tuples in parallel;
monitoring performance of the streaming application;
when performance of the streaming application indicates processing data tuples in parallel by the first set of operators and the second set of operators is no longer needed, determining which of the first virtual machine and second virtual machine is least performing;
and
when the least performing virtual machine can be torn down, tearing down the least performing virtual machine.
