---------------------------------------
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.
