Alexander Lapin updated IGNITE-24375:
-------------------------------------
Description:
h3. Motivation
Instead of table assignments, PD should track zone assignments: ones with
prefix zones ZoneRebalanceUtil#PENDING_ASSIGNMENTS_PREFIX and thus elect one of
zone's replicas as primary one. Please pay attention that colocation specific
PrimaryReplicaChangeCommand processing is expected to be implemented in
separate ticket IGNITE-24374
h3. Definition of Done
* Instead of TestPlacementDriver common one is used in majority of colocation
tests. Some tests require primary replica changes that are easier to enforce
using test placement driver.
* Depending on whether collocation is enabled or not PD tracks either zone's
assignments or table's ones. Not sure whether it's better to switch that inside
PD or start different PD within Ignite Node start procedure.
