The invention belongs to the technical field of water conservancy projects, and provides a dam mass data distributed processing method based on a cloud computing architecture, which comprises the following steps: S1, performing unified access and standardized description on multi-source heterogeneous dam monitoring data, and generating a structured data object with a spatio-temporal index; s2, performing adaptive data fragmentation and distributed storage optimization based on space-time attributes and access features of the data objects; s3, according to the characteristics and resource requirements of the computing tasks, constructing a dynamic extensible parallel computing workflow; s4, in the process of executing the parallel computing workflow, implementing resource flexible scheduling and task migration based on load feedback; and S5, performing multi-dimensional aggregation on the processing result, and feeding back to the data storage layer.

The invention discloses a dynamic replacement method and device for a static resource URL and a computer program product, a Proxy proxy object is created for the static resource URL through an innovative JavaScript proxy mechanism, then a get trap in the Proxy proxy object is utilized to determine an optimal CDN resource domain name from an alternative static resource library after a CDN resource access request is received, and then the optimal CDN resource domain name is replaced by the optimal CDN resource domain name in the alternative static resource library. On the basis of the optimal CDN resource domain name, an optimal static resource URL can be generated; and finally, replacing the original static resource URL by using the optimal static resource URL, thereby completing the dynamic replacement of the original static resource URL. By means of the design, compared with a traditional technology, manual intervention is not needed, the cost is reduced, the configuration efficiency is improved, meanwhile, dynamic selection of the optimal CDN node is achieved, the resource loading speed can be guaranteed, and then the operation performance is improved; therefore, the method is very suitable for large-scale application and popularization.

The embodiment of the invention relates to a network access processing method and device, equipment and a medium. The method comprises the following steps: detecting whether terminal equipment generates a network registration request or not; after the network registration request is detected, whether initial registration information corresponding to the network registration request is matched with a preset database is determined, and the preset database comprises at least one piece of historical registration information which is rejected to be registered in a historical registration scene; and when the initial registration information is successfully matched with the preset database, updating the initial registration information, and sending a network registration request to the access network according to the updated registration information. According to the technical scheme, early warning is carried out on the off-network event of the terminal equipment, and switching of the network registration information is carried out in time before possible off-network is early warned, so that the network access performance is ensured.

The embodiment of the invention provides a data processing method and device, electronic equipment and a storage medium, the method is applied to a database system, and a hot storage layer and a cold storage layer are mounted on the database system; the method comprises the steps of obtaining access logs and metadata change logs of N pieces of first data in a first time period; through a pre-trained prediction model, a first probability of each piece of first data is obtained according to the access log and the metadata change log, and the first probability represents a probability that the first data belongs to hot data or cold data; determining hot data and / or cold data in the N pieces of first data according to the first probability of the N pieces of first data; and performing a migration operation on the hot data and / or the cold data to enable the hot data to be stored in the hot storage layer and the cold data to be stored in the cold storage layer. Therefore, according to the embodiment of the invention, the problem that the architecture of the existing database storage system cannot consider both the storage cost and the data query performance can be solved.
