Description

CorruptedZoneShardKey: The routing table contains a zone with a min key or max key that doesn't correspond to the collection shard key.
New in version 7.0.

Format

{
   type: "CorruptedZoneShardKey",
   description: "<string>",
   details: {
      namespace: "<string>",
      collectionUUID: UUID("<uuid>"),
      zone: <zone>,
      shardKeyPattern: <pattern>
   }
}

CorruptedZoneShardKey inconsistency documents contain the following fields:

Field	Type	Description
`type`	string	Type of inconsistency document. Returns a value of `CorruptedZoneShardKey` 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 with the corrupted zone shard key.
`details.zone`	document	Zone with the corrupted shard key.
`details.shardKeyPattern`	document	Collection shard key pattern.

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 CorruptedZoneShardKey inconsistency document:

{
   cursor: {
      id: Long("0"),
      ns: "test.$cmd.aggregate",
      firstBatch: [
         {
            type: "CorruptedZoneShardKey",
            description: "Found zone with a shard key pattern violation",
            details: {
               namespace: "test.authors",
               collection: {
                  collectionUUID : new UUID("1ad56770-61e2-48e9-83c6-8ecefe73cfc4"),
                  zone : {
                     ns : "test.authors",
                     tag: "64ddd81656be208c6685da21",
                     min: {
                        y: 0
                     },
                     max: {
                        x: MaxKey
                     }
                  },
                  shardKeyPattern: {
                     x: 1
                  }
               }
            }
         }
      ],
   },
   ok: 1
}
