Description
The system.sharding_ddl_coordinators is a local collection containing metadata on outstanding DDL operations coordinated by the shard that hosts it: for specific DDLs (movePrimary and soon createCollection), such metadata contain references to other shard IDs participating in a request.
The restore procedure should adapt the values of these shard IDs to the topology of the destination cluster to ensure that outstanding operations will be correctly resumed and completed.
