{{tConfig.setIdleStateRetentionTime(Time.hours(12), Time.hours(24))}}
{{}}
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.
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. Set to 0
(zero) to never clean-up the state.
maxTime – The maximum time interval for which idle state is retained. Must be
at least 5 minutes greater than minTime. Set to 0 (zero) to never clean-up the
state
