Vladislav Pyatkov updated IGNITE-20485:
---------------------------------------
Description:
*Motivation*
Currently, the lease interval depends on the lease update frequency and is
calculated like this:
{code:title=LeaseUpdater.java}
private static final long LEASE_INTERVAL = 10 * UPDATE_LEASE_MS;
{code}
The interval is impossible to configure; that way, it makes the test longer
than it can be with a short lease interval.
*Implementation notes*
* Create a new property root to configure. The property has to be specified for
the placement driver only (PlacementDriverConfigurationScema).
* The property should be configured for the entire cluster
(ConfigurationType#DISTRIBUTED).
* The property may change on the alive cluster. The placement driver manager
has to handle configuration updates.
* The property should calculate two parameters: the lease interval and the long
lease interval (LeaseUpdater#LEASE_INTERVAL, LeaseUpdater#longLeaseInterval).
The frequency of checking leases is being evaluated based on the lease interval
(LeaseUpdater#UPDATE_LEASE_MS).
* In addition to the tuning ability through the configuration framework, we
should provide a configuration through system properties to use in tests. Add
the system property for the lease interval only, because for the long lease
interval, the property already exists.
* Do not forget to check TODOs.
*Definition of done*
Allow to configure lease intervat at least the system properties to use in the
test.
Also, the ability to configure should be available through the Ignite property.
