使用方法

This extension provide experimental features for timescaledb, check the docs for details.

Features

The following links lead to pages for the different features in the TimescaleDB Toolkit repository.

  • ASAP Smoothing experimental - A data smoothing algorithm designed to generate human readable graphs which maintain any erratic data behavior while smoothing away the cyclic noise.

  • Hyperloglog experimental – An approximate COUNT DISTINCT based on hashing that provides reasonable accuracy in constant space. (Methods)

  • LTTB experimental – A downsample method that preserves visual similarity. (Methods)

  • Percentile Approximation - A simple percentile approximation interface [(Methods)], wraps and simplifies the lower level algorithms:

    • T-Digest – A quantile estimate sketch optimized to provide more accurate estimates near the tails (i.e. 0.001 or 0.995) than conventional approaches. (Methods)
    • UddSketch – A quantile estimate sketch which provides a guaranteed maximum relative error. (Methods)
