Kirill Gusakov updated IGNITE-21806: ------------------------------------ Description: *Motivation* When the IGNITE-18991 we will have ZonePartitionId oriented management inside the PlacementDriver, but still have the number of replicas, which equals to the number of tables per partition in the zone. As a iterative step on the road of "zone based collocation (one RAFT group per zone partition" we must implement the another approach: one PrimaryReplica for many tables partitions inside the zone. So, in the case of 2 tables inside the 1 zone we must have 1 PrimaryReplica per partition. *Definition of done* Prepare design and according ticket breakdown for the feature implementation was: *Motivation* When the IGNITE-18991 we will have ZonePartitionId oriented management inside the PlacementDriver, but still have the number of replicas, which equals to the number of tables per partition in the zone.
