postgresql-hll
PostgreSQL extension adding HyperLogLog data structures as a native data type
This Postgres module introduces a new data type hll which is a HyperLogLog data structure. HyperLogLog is a fixed-size, set-like structure used for distinct value counting with tunable precision. For example, in 1280 bytes hll can estimate the count of tens of billions of distinct values with only a few percent error. In addition to the algorithm proposed in the original paper, this implementation is augmented to improve its accuracy and memory use without sacrificing much speed. See below for more details. This postgresql-hll extension was originally developed by the Science team from Aggregate Knowledge, now a part of Neustar. Please see the acknowledgements section below for details about its contributors.
