| BloomFilter | A Bloom filter is a space-efficient probabilistic data structure that offers an approximate
 containment test with one-sided error: if it claims that an item is contained in it, this
 might be in error, but if it claims that an item is not contained in it, then this is
 definitely true. | 
| CountMinSketch | A Count-min sketch is a probabilistic data structure used for cardinality estimation using
 sub-linear space. |
