Sergey Uttsel updated IGNITE-19506:
-----------------------------------
Description:
h3. *Motivation*
Need to use data nodes from DistributionZoneManager instead of
BaselineManager#nodes in all places except of in-memory raft
(TableManager#calculateAssignments)
We need to get data nodes consistently so we need to use revision of
configuration events and a meta storage events as causality token.
Description of causality data nodes algorithm is attached.
h3. *Definition of Done*
Implement method DistributionZoneManager#dataNodes to obtaining data nodes from
zone manager with causality token.
Use this method instead of BaselineManager#nodes.

h3. *Motivation*
Need to use data nodes from DistributionZoneManager instead of
BaselineManager#nodes in:
# DistributionZoneRebalanceEngine#onUpdateReplicas
# TableManager#createAssignmentsSwitchRebalanceListener
We need to get data nodes consistently so we need to use revision of
configuration events and a meta storage events as causality token. Also need to
use VersionedValue to save data nodes with causality token.
Description of causality data nodes algorithm is attached.
h3. *Definition of Done*
DistributionZoneRebalanceEngine#onUpdateReplicas and
TableManager#createAssignmentsSwitchRebalanceListener use data nodes from
DistributionZoneManager
