Abstract

The invention discloses a dynamically telescopic filtering method and device, computer equipment and a storage medium, and relates to a filtering system. The method comprises the following steps: recording creation time and update time of each filter; when the time difference between the updating time of each filter and the current time exceeds a preset updating threshold value, deleting the filter; when the storage capacity of the newly created filter exceeds the set storage capacity of the newly created filter; obtaining the total number of the current filters; if the total number of the current filter exceeds a preset number threshold value, performing filtering; if the difference between the current time and the creation time of the newly created filter is within the first preset timethreshold value, creating the newly created filter , and setting the set storage capacity of the new filter to be larger than the set storage capacity of the newly created filter. The storage space isreduced, and the storage efficiency is improved.

Description

technical field [0001] The invention relates to the field of filtering systems, in particular to a dynamically scalable filtering method, device, computer equipment and storage medium. Background technique [0002] In the recommendation system, there will be the problem of repeated exposure of the content that has been played and exposed, so a filtering system is required to filter these contents. Traditional filtering systems include: Bloom Filter (Bloom filter), CountingBloom Filter (counting Bloom filter), D-left Counting Bloom Filter (D-left counting Bloom filter), Cuckoo Filter (cuckoo filter) ), these filtering systems support the deletion of historical data, but the storage overhead is large, and they cannot support dynamic scaling of storage capacity. Contents of the invention [0003] Embodiments of the present invention provide a dynamically scalable filtering method, device, computer equipment, and storage medium, aiming at solving the problem of large storage ...
