Method and device for allocating streaming data

The invention provides a method and device for allocating the streaming data. The method comprises the following steps of acquiring the current health degree, the previous health degree and the current success rate of each streaming data processing resource; for each streaming data processing resource, based on the current health degree and the previous health degree of the streaming data processing resource, determining a current load expected variable quantity of the streaming data processing resource; determining the current load expectation quantity of each streaming data processing resource based on the current success quantity and the current load expectation change quantity of each streaming data processing resource; determining a first data distribution probability of each streaming data processing resource based on the current load expectation quantity of each streaming data processing resource; and distributing the streaming data to the corresponding streaming data processingresource in each streami
