v2.2.0 (December 2019)

• Added functionality

  • Bloom
    • #149 BF.INFO returns details about a specific bloom filter
    • Scalable
      • #153 Ability to change the EXPANSION rate. This means each subsequent sub-filter will be expansion times larger as the previous one.
      • #160 Optimise the scaling up of filter according to the Scalable Bloom Filter paper
      • #161 Optional NONSCALING argument to disable scaling. (This saves space since less hash functions are used)
    • #155 Disabling rounding up functionality
  • Cuckoo
    • #149 CF.INFO returns details about a specific cuckoo filter
    • Scalable
      • #138 Configurable EXPANSION. When an additional filter is created, its size will be the size of the current filter multiplied by the expansion. Higher expansion rates will result in lower error rates.

      • #131 Configurable MAXITERATIONS. Number of attempts to swap buckets before declaring filter as full and creating an additional filter.
