Abstract

The embodiment of the invention discloses a data deletion method, device, computer equipment and storage medium. The invention is applied to the field of data query in big data. The method includes: if it is detected that the time series data is written, judging whether the time stamp of the time series data is in the time period corresponding to the current Bloom filter; if the time stamp of the time series data is not in the time corresponding to the current Bloom filter In the period, a new Bloom filter is established according to the next time period corresponding to the timestamp of the time series data, and the time series data in the next time period is written into the new Bloom filter; according to the established Bloom filter The number of filters determines whether there is an expired Bloom filter; if there is an expired Bloom filter, delete the expired Bloom filter. By implementing the method of the embodiment of the present invention, the deletion operation of the Bloom filter can be realized, the application of the Bloom filter to time series data can be extended, and the space efficiency and query efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data deletion method, device, computer equipment and storage medium. Background technique [0002] With the development of information and technology, huge amounts of data are constantly being generated in people's daily life. The value of data is getting more and more attention, and the processing of data is becoming more and more important. Traditional data query methods usually store data in disks, and then query them through linked lists, trees, and hash tables. The time is getting longer and longer, resulting in large space consumption and low query efficiency. The existing Bloom filter (Bloom Filter) is an algorithm to quickly determine whether an element exists in the set, which has the advantages of high space efficiency and high query efficiency, but in the process of processing time series data, the time series data Deduplication usually requires deleting ex...
