> We need to calculate the average queue size / free executor size for a window to have good data for making routing decisions.
> Interesting things to consider:
>  * The time gap between arriving request can be different, so simple average is not enough to have correct data
>  * We need to have 2 parameters
>  ** Time window length
>  ** Maximum data point numbers - so we will not collect "infinite" amount of data at high load
