[jira] [Created] (IGNITE-16010) setBaseline method must write new baseline to metastore

Kirill Gusakov created IGNITE-16010:
---------------------------------------

             Summary: setBaseline method must write new baseline to metastore
                 Key: IGNITE-16010
                 URL: https://issues.apache.org/jira/browse/IGNITE-16010
             Project: Ignite
          Issue Type: Sub-task
            Reporter: Kirill Gusakov


Current org.apache.ignite.Ignite#setBaseline method updates assignments directly and does not save baseline as a separate source of truth anywhere.

Instead, it should store new baseline configuration to metastore (in future it can be baseline per table). This metastore key update will be a trigger for listeners to update appropriate assignments.

This approach provides the generalized way of baseline changing and further processing of this event by rebalancing the algorithm, for example.
