Cleaning Up Expired Rules
When the method server starts, the expired predictive replication rules are automatically cleaned up. The cleanup schedule has a default frequency of 1 day, which means that the cleanup operation happens every day.
The expiration of predictive replication rules is determined by the following property:
wt.fv.predictiveReplicationDuration
This property determines the duration for which the predictive replication rules run, and the unit of measure is days. The default value is 90 days.
The expiration date of a predictive replication rule is determined based on the creation date of the rule and the duration set in the wt.fv.predictiveReplicationDuration property. If the property is set to 90 days and a rule was created more than 90 days ago, the rule is considered expired and is deleted during the cleanup process.
