Abstract
A streams manager clones a portion of a primary flow graph to a virtual machine with a buffer to assure no data is lost if the corresponding portion of the primary flow graph fails. The buffer can be on the input of the cloned portion or on the output of the cloned portion. Cloning a portion of a primary flow graph with a buffer assures no data is lost when the corresponding portion of the primary flow graph fails. When the primary flow graph recovers from the failure, the processing may be switched back to the primary flow graph, which causes the buffer to begin buffering once again.
