The derby.replication.maxLogShippingInterval property specifies, in milliseconds, the longest interval between two consecutive shipments of the transaction log from the master to the slave.
This property provides a "soft" guarantee that the slave will not deviate more than this number of milliseconds from the master.
The value specified for the derby.replication.maxLogShippingInterval property must be at least ten times the value specified for the derby.replication.minLogShippingInterval property. If you set derby.replication.maxLogShippingInterval to a lower value, Derby changes the derby.replication.minLogShippingInterval property value to the value of the derby.replication.maxLogShippingInterval property divided by 10.
5000 milliseconds (5 seconds).
derby.replication.maxLogShippingInterval=10000
This property is static; if you change it while Derby is running, the change does not take effect until you reboot.
