Request

The request body can either be empty or include a recovery plan.

If the request body is empty, the database will be recovered automatically:

  • Databases with no persistence are recovered with no data.

  • Persistent files such as AOF or RDB will be loaded from their expected storage locations where replica or primary shards were last active.

  • If persistent files are not found where expected but can be located on other cluster nodes, they will be used.
