# 范围策略
sh.shardCollection("articledb.author",{"age":1})

基于范围的分片方式与基于哈希的分片方式性能对比：基于范围的分片方式提供了更高效的范围查询,给定一个片键的范围,分发路由可以很简单地确定哪个数据块存储了请求需要的数据,并将请求转发到相应的分片中. 不过,基于范围的分片会导致数据在不同分片上的不均衡,有时候,带来的消极作用会大于查询性能的积极作用.比如,如果片键所在的字段是线性增长的,一定时间内的所有请求都会落到某个固定的数据块中,最终导致分布在同一个分片中.在这种情况下,一小部分分片承载了集群大部分的数据,系统并不能很好地进行扩展. 与此相比,基于哈希的分片方式以范围查询性能的损失为代价,保证了集群中数据的均衡.哈希值的随机性使数据随机分布在每个数据块中,因此也随机分布在不同分片中.但是也正由于随机性,一个范围查询很难确定应该请求哪些分片,通常为了返回需要的结果,需要请求所有分片. 如无特殊情况，一般推荐使用 Hash Sharding。而使用 _id 作为片键是一个不错的选择，因为它是必有的，你可以使用数据文档 _id 的哈希作为片键。这个方案能够是的读和写都能够平均分布，并且它能够保证每个文档都有不同的片键所以数据块能够很精细。似乎还是不够完美，因为这样的话对多个文档的查询必将命中所有的分片。虽说如此，这也是一种比较好的方案了。

db.printShardingStatus()

# 查看均衡器是否工作（需要重新均衡时系统才会自动启动，不用管它）：
sh.isBalancerRunning()

# 查看当前Balancer状态
sh.getBalancerState()

提示：js的语法，因为mongo的shell是一个JavaScript的shell。
