MongoDB Error 283: Invalid Shard Key Update
Description
This error occurs when an operation attempts to modify a document in a way that would change its owning shard. In a sharded cluster, a document's shard key is immutable and cannot be altered after insertion, as this would violate the data distribution rules.
Error Message
Would Change Owning Shard
Known Causes
3 known causesAttempted Shard Key Modification
An update operation tried to modify a field that is part of the collection's shard key, which is immutable for existing documents in a sharded cluster.
Incorrect Application Logic
Application code might be attempting to 'move' a document between shards by changing its shard key, rather than allowing MongoDB's internal chunk migration processes.
Metadata Inconsistency
In rare cases, inconsistencies in sharding metadata could lead to the cluster incorrectly identifying shard ownership during an operation.
