commitReshardCollection (database command数据库命令)

Definition定义

commitReshardCollection

New in version 5.0.在版本5.0中新增。

During a resharding operation, MongoDB does not block writes until the estimated duration to complete the resharding operation is below two seconds.在重新标记操作期间，MongoDB不会阻止写入，直到完成重新标记操作的估计持续时间低于两秒。

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.如果当前的估计值超过两秒，但时间框架对您来说是可以接受的，您可以更快地完成换牌。commitReshardCollection命令阻止早期写入并强制完成重新标记操作。

Tip

In mongosh, this command can also be run through the sh.commitReshardCollection() helper method.在mongosh中，此命令也可以通过sh.commitReshardCollection()辅助方法运行。

Helper methods are convenient for mongosh users, but they may not return the same level of information as database commands. 助手方法对mongosh用户来说很方便，但它们可能不会返回与数据库命令相同级别的信息。In cases where the convenience is not needed or the additional return fields are required, use the database command.如果不需要便利性或需要额外的返回字段，请使用database命令。
