Abstract
A method for updating a stable cuckoo filter used for membership testing of data streams, executed by a processor, is described. The method includes the steps of: performing a first hash on a first element to be inserted into the stable cuckoo filter to determine a first candidate bucket; performing a second hash on a fingerprint of the first element to determine a second candidate bucket; selecting a target candidate bucket from a group consisting of the first candidate bucket and the second candidate bucket; inserting the first element into the target candidate bucket; updating the stable cuckoo filter according to one or more of a random update strategy, an insertion failure update strategy, a scanning strategy, a skip scanning update strategy, a blocked design strategy and a local time-sensitive update strategy; and obtaining an updated stable cuckoo filter.
