TimescaleDB hyperfunctions are a series of SQL functions within TimescaleDB that make it easier to manipulate and analyze time-series data in PostgreSQL with fewer lines of code. You can use hyperfunctions to easily aggregate data into consistent buckets of time, calculate percentile approximations of data, compute time-weighted averages, downsample and smooth data, and perform faster COUNT DISTINCT queries using approximations.

Hyperfunctions are “easy” to use: you call a hyperfunction using the same SQL syntax you know and love.
