Abstract
A method for optimizing memory usage for a hyperloglog (HLL) estimator is disclosed. When a multiset is applied to an HLL estimator, a sparse representation of a sketch may be created. The sparse representation may be sorted whenever a total number of buckets in the sparse representation is evenly divisible by a sorting threshold and is also less than a transition threshold. The sparse representation may be converted to a dense representation when the number of buckets in the sparse representation reaches the transition threshold.
