Calculators received new parameter - update_period.
It specifies validity period for the generated intervals and covers any update to the intervals - due to new messages or manual parameter changes in calculator. Any interval which end time lays outside of specified update_period (in seconds from current moment of time) will be ignored.
The default value for update_period is 365 days and we recommend to keep in balance next formula:
update_period < messages_ttl (in devices) < intervals_ttl.
For example you may set update_period to 30 days, messages_ttl to 90 days (to keep original messages from devices up to 90 days) and intervals_ttl to 10 years - to keep lightweighed report results for up to 10 years.
One important notice is that if you want to change calculator settings and want system to resync all current intervals according to new settings you should set update_interval >= intervals_ttl to cover whole range.
