对于空的或不存在的collection,指定了区域和区域范围(从 MongoDB 4.0.3 开始可用), 分片操作为定义的区域范围创建空数据段以及任何附加数据段以覆盖分片键值的整个范围,并根据区域范围执行初始数据段分发。数据段的初始创建和分发可以更快地设置区域分片。

仅活动 mongos 实例的版本和数量。 默认的详细值为false。 有关输出的详细信息,请参阅sh.status()(mongosh方法)。 注意 在mongosh中运行的db.printShardingStatus()方法不返回JSON。使用db.printShardingStatus()进行手动检查,在脚本中使用配置数据库。
