Postgresql Hll
PostgreSQL extension adding HyperLogLog data structures as a native data type
About
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.
