The invention discloses a fault processing method and device, electronic equipment and a storage medium, and relates to the technical field of computers. A specific embodiment of the method comprises the following steps: in response to a processing instruction of a fault task node, obtaining node information of the fault task node to determine a corresponding fault recovery strategy and trigger the fault recovery strategy; responding to a fault recovery strategy which is a fault node recovery strategy, establishing a replacement task node corresponding to the fault task node, and querying a working state of an upstream task node corresponding to the fault task node; in response to the working state being the preset state, sending a starting instruction to the replacement task node; and in response to the fact that the working state is not the preset state, after it is monitored that the working state of the upstream task node corresponding to the fault task node is updated to the preset state, sending a starting instruction to the replacement task node. According to the embodiment, the problem that after a single task node in the Flink breaks down, all the task nodes need to be redeployed, and the effectiveness of service data processing is reduced can be solved.
Description
technical field [0001] The present invention relates to the field of computer technology, and in particular, to a fault handling method, device, electronic device and storage medium. Background technique [0002] In recent years, with the vigorous development of big data technology, business processing requires more real-time main components, and more and more businesses begin to adopt real-time processing methods to accelerate business development. Flink (a stream processing framework) is widely used as a real-time processing engine due to its high throughput, low latency, and good fault tolerance. Flink processes business data through multiple task nodes. After a single task node fails, all task nodes need to be redeployed. During the task node redeployment phase, Flink cannot process business data, thus reducing the effectiveness of business data processing. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present invention provide a fault proc...
