commitReshardCollection
New in version 5.0.
During a resharding operation, MongoDB does not block writes until the estimated duration to complete the resharding operation is below two seconds.
If the current estimate is above two seconds but the time frame is acceptable to you, you can finish resharding faster. The
commitReshardCollection
command blocks writes early and forces the resharding operation to complete.Tip
In
mongosh
, this command can also be run through thesh.commitReshardCollection()
helper method.Helper methods are convenient for
mongosh
users, but they may not return the same level of information as database commands. In cases where the convenience is not needed or the additional return fields are required, use the database command.
Syntax
The command has the following syntax:
db.adminCommand( { commitReshardCollection: "<database>.<collection>" } )
The mongosh
provides a wrapper method
sh.commitReshardCollection()
.
Example
Commit a Resharding Operation
The following command forces the resharding
operation on the sales.orders
to block writes
and complete:
db.adminCommand({ commitReshardCollection: "sales.orders" })
