Bug Fix⚓︎

Cluster operations⚓︎

  • Fixed HDX Scaler to handle correctly the effects of newly merged-tunables. Earlier, it would continue watching stale metrics, which prevented scaling decisions.
  • Corrected the cool-down window calculation for HDX Scaler. Now compute from the most recent scaling event regardless of direction, up or down.
