Vyacheslav Koptilin reassigned IGNITE-21806:
--------------------------------------------
Assignee: Kirill Gusakov
> One PrimaryReplica for many tables partitions inside the one zone
> -----------------------------------------------------------------
>
> Key: IGNITE-21806
> URL: https://issues.apache.org/jira/browse/IGNITE-21806
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Gusakov
> Assignee: Kirill Gusakov
> Priority: Major
> Labels: ignite-3
>
> *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*
> If the zone has N tables with M partitions, it must have M PrimaryReplicas -
> one PrimaryReplica per zone partition.
