LDCF

The Logarithmicl Dynamic Cuckoo Filter (LDCF) is an efficient approximate membership test data strucutre for dynamic big data sets. LDCF uses a novel multi-level tree structure and reduces the worst insertion and membership testing time from O(N) to O(1), where N is the size of the set. At the same time, LDCF reduces the memory cost of DCF as the cardinality of the set increases.

Environment

We implement DCF with an Intel(R) Core(TM) i5-2430M CPU @2.4GHz and OpenSSL library environment.

Install OpenSSL (Please refer to https://www.openssl.org to learn more).

sudo apt-get install openssl
sudo apt-get install libssl-dev

Build and run the example

cd src/
make test
./test

Configurations

Configurations including false pisitive, item number can be costomized in "configuration/config.txt".

false positive = 0.01
item number = 100000000
