This invention relates to the field of classifying rotating equipment in refining and chemical enterprises, and provides a method and apparatus for classifying rotating equipment in refining and chemical enterprises. The method includes: determining the severity score and single-point failure / non-single-point failure score of various failure consequence indicators for each rotating equipment in the refining and chemical enterprise; calculating the risk priority number of each rotating equipment based on the severity score, single-point failure / non-single-point failure score, and weight of each failure consequence indicator; and determining the risk level of each rotating equipment based on its risk priority number. This invention can improve the accuracy of rotating equipment risk levels and provide a scientific and reasonable basis for the classified management of rotating equipment in enterprises. It can also provide a reference for rotating equipment maintenance measures and the allocation of maintenance resources.

The application discloses a Bcache dirty key based on cache optimization method and system, and belongs to the technical field of computer storage. The application establishes a dirty key cache linked list, synchronously inserts reference information into the linked list when the dirty key is inserted into a B-tree, and maintains according to an LRU strategy; according to the proportion of the total number of dirty keys and the capacity of the cache linked list, a full cache mode or a partial cache mode is dynamically switched; when the dirty key is searched, the cache linked list is preferentially traversed, and when a miss occurs or the partial cache mode is used, the B-tree full tree scanning is used. The application also contains adaptive memory management, graceful degradation and write-back batch optimization. By using the application, invalid traversal of the B-tree can be greatly reduced, write-back operation can be avoided to block business IO, the efficiency of dirty key searching and write-back can be significantly improved, and backward compatibility is maintained.

The application reduces the development threshold through standardized packaging, accelerates application innovation through visual arrangement, and improves resource utilization efficiency through multi-dimensional charging; the application has high stability and adaptability, and realizes efficient operation and large-scale development of low-altitude economy services.

This application belongs to the fields of big data and fintech, and is applied to the field of batch processing of insurance policy fees. It relates to a task batch processing method, apparatus, computer equipment, and storage medium, including receiving a batch processing request; obtaining a configuration file; identifying unused configuration text segments in the current batch processing; optimizing and adjusting the batch processing task logic; deploying the optimized and adjusted task logic and configuration file to several batch processing systems; processing fee change information in segments; parsing each piece of fee change information, and using the parsing results as method execution parameters to execute the batch processing task. This application optimizes and adjusts the task logic through configuration files and uses a modulo method to process all fee change information in segments, ensuring that each fee change information is distributed to its corresponding batch processing system. This optimizes task batch processing, improves batch processing efficiency, ensures reasonable utilization of server resources, and avoids system crashes caused by batch processing events.

The invention relates to the technical field of flow aggregation, in particular to a multistage homologous session flow aggregation method and system, and the method comprises the steps: extracting quintuple information of each data packet, generating a session identifier, and calculating a session feature vector and a session priority score; at the first aggregation level, each service interface board establishes a local session table; preferentially performing aggregation processing on the data packets of the high-priority sessions according to the session priority scores; at a second aggregation level, each service interface board synchronizes the local session table to a case-level session table; forwarding the data packets with the same session identifier to the same output port; at a third aggregation level, synchronizing the case-level session table to a global session table; redirecting the data packets on other cases to a corresponding output port of the main aggregation node determined according to the session affinity; outputting all the data packets of the same session identifier from the same output port and generating a session integrity report; therefore, the integrity and consistency of the session data are ensured.
