When an in-place restore of a multi-node PostgreSQL HA cluster to a previous point in time is triggered through NDB, how does NDB handle the Patroni consensus layer during the recovery process?

A.

NDB promotes all cluster nodes to simultaneous read-write primary leaders to accelerate the ingestion of archived transaction logs.

B.

NDB leaves Patroni fully active so that it can stream live application traffic to the standby nodes while the primary is being overwritten.

C.

NDB temporarily pauses Patroni cluster monitoring and places the cluster in maintenance mode during the restore operation.

D.

NDB deletes the Patroni configuration and recreates it from backup after the restore has completed.
