> Thanks for sharing the insight on `config.getScaleActionStartDelayMillis()`, @jtuglu1 ! Can you share some typical values that you use for this config, and how it compares to the scale action period? We typically set a submit (start) delay of 20mins. This allows the scaler to recover before scaling (because often times, scaling too frequently will disrupt lag more than it helps). Instead, we opt to try and let the lag recover under 20mins, and if there's a sustained decrease in read tput (either due to new column) or increase in write tput, we allow the scaler to scale. Scale action period is typically much smaller, maybe 5-10mins. -- This is an automated message from the Apache Git Service.
