sh.moveChunk(collection, query, destination)
| 参数: |
- collection (string) – Specify the sharded collection containing
the chunk to migrate.
- query – Specify a query to identify documents in a specific
chunk. Typically specify the shard key for a
document as the query.
- destination (string) – Specify the name of the shard that you
wish to move the designated chunk to.
|
|---|
Moves the chunk containing the documents specified by the query
to the shard described by destination.
This function provides a wrapper around the
moveChunk. In most circumstances, allow the
balancer to automatically migrate chunks,
and avoid calling sh.moveChunk() directly.
