At the moment, the rule is as follows:
The background purge task runs periodically with the following frequency:
- If the maximum age has a higher value than 86400 seconds (24 hrs), it will run every 24 hours starting from when the LW Edge service started.
- If the maximum age has a lower value than 86400 seconds (24 hrs), it will run periodically at the maximum age value specified starting from when the LW Edge service started.
This is made to ensure that purge is not performed too often and won't impact the system performance.
