Description

MissingRoutingTable: A sharded collection exists without a routing table.
New in version 7.0.

Format

{
   type: "MissingRoutingTable",
   description: "<string>",
   details: {
      namespace: "<string>",
      collectionUUID <uuid>
   }
}

MissingRoutingTable inconsistency documents contain the following fields:

Field	Type	Description
`type`	string	Type of inconsistency document. Returns a value of `MissingRoutingTable` for this inconsistency type.
`description`	string	Describes the nature of the inconsistency found in the metadata.
`details`	document	Document with additional information on where the inconsistency exists in the database and sharded cluster.
`details.namespace`	string	Indicates the database and collection where the inconsistency exists.
`details.collectionUUID`	UUID	UUID of the collection without the routing table.

Example

Use the db.adminCommand() method to call the checkMetadataConsistency command:

db.adminCommand( { checkMetadataConsistency: 1 } )

The method returns a cursor with a batch of documents showing the inconsistencies found in the sharding metadata. The example below shows a cursor with a MissingRoutingTable inconsistency document:

{
   cursor: {
      id: Long("0"),
      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "MissingRoutingTable",
            description: "There is a sharded collection without routing table",
            details: {
               namespace: "test.authors",
               collectionUUID: new UUID("1ad56770-61e2-48e9-83c6-8ecefe73cfc4")
            }
         }
      ],
   },
   ok: 1
}
