/**
 * Specifies a minimum and a maximum time interval for how long idle state, i.e., state which
 * was not updated, will be retained.
 * 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.
 *
 * <p>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.
 *
 * <p>Set to 0 (zero) to never clean-up the state.
 *
 * <p>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.
