Embodiment 1
[0040] Example 1: Cold area data loading (risk data loading)
[0041] The method of loading risk data from cold area data is as follows: split N tasks to execute database query every morning; obtain query results and store risk data one by one in the Bloom filter; store the binary file generated by the Bloom filter in the file server; After the execution is completed, notify the application system to load the files generated by N tasks; the application system loads the files into the local risk data Bloom filter array; the application system deletes the Bloom filter array of the last risk data and enables the current risk data Array of filters. Wherein, N is an integer greater than or equal to 2.
Embodiment 2
[0042] Example 2: Load when hot zone data is added (risk data loading)
[0043] The method of loading risk data when hot area data increases is as follows: the application system has a request to increase risk data; upon receiving the new request, notify all application systems to add to the local risk data Bloom filter.
Embodiment 3
[0044] Example 3: Loading when hot zone data is deleted (risk data loading)
[0045] The method of loading risk data when hot zone data is deleted is as follows: the application system has a request to delete risk SMS; upon receiving the delete request, load all the data deleted on the day and store them in the Bloom filter; generate a binary file from the content of the Bloom filter ;Notify all application systems to load the binary file into the H-R area.
