State will never be > cleared until it was idle for less than the minimum time and will never be > kept if it was idle for more than the maximum time. > When new data arrives for previously cleaned-up state, the new data will be > handled as if it was the first data. This can result in previous results > being overwritten. > Set to 0 (zero) to never clean-up the state. > NOTE: Cleaning up state requires additional bookkeeping which becomes less > expensive for larger differences of minTime and maxTime. The difference > between minTime and maxTime must be at least 5 minutes. > NOTE: Currently maxTime will be ignored and it will automatically derived > from minTime as 1.5 x minTime. > Deprecated > use setIdleStateRetention(Duration) instead. > Params: > minTime – The minimum time interval for which idle state is retained.
