v.23.12New Feature

Add seriesPeriodDetectFFT function for period detection using FFT

Official CH changelog text
Add a new function seriesPeriodDetectFFT to detect series period using FFT. #57574 (Bhavna Jindal).
Introduces a new function seriesPeriodDetectFFT that detects the period of a time series using Fast Fourier Transform (FFT).

Why it matters

This feature enables users to automatically identify the periodicity in time series data, facilitating better analysis and understanding of recurring patterns without manual inspection.

How to use it

Use the function seriesPeriodDetectFFT in your queries by passing the time series data as input. The function applies FFT to detect and return the dominant period in the series.
