Hyperloglog is an approximate technique for computing the number of distinct entries in a set.
Hyperloglog is an approximate technique for computing the number of distinct entries in a set implemented in Algebird, a scala library for abstract algebra. This can be used in Summingbird to create MapReduce programs for estimating cardinalities of large datasets in streaming (online) or batch (offline) mode. Data structure store Redis also has HyperLogLog implementation.
