DSP Algorithm Principles and Application in Crane Predictive Autoscaling
The article details how Tencent Cloud’s Crane predictive autoscaling leverages a digital signal processing pipeline—transforming Prometheus time‑series data via Fourier analysis, using DFT/FFT to identify periodic patterns, predict load with IFFT, and configure margins, thresholds, and spectrum parameters to overcome HPA’s reactive limits.
