In some cases, they can also be used to satisfy read requests to offload the primary shard.
在某些情况下，它们可以用来满足读取请求卸载主碎片。
The shard ID will be mapped with respect to the virtual shard ID map configured in the later steps.

Getting back to the familiar example of my racing application, I can shard by race or by runner.
现在让我们回到我经常提到的赛跑应用程序示例中，我可以根据比赛或参赛者进行切分。
Namely, it needs a shard-access strategy, a shard-selection strategy, and a shard-resolution strategy.
比如，需要一个切分访问策略、一个切分选择策略和一个切分处理策略。
In case a virtual shard id map is not provided (it is optional), it is defaulted to the physical shard id map.
如果未提供虚拟碎片ID映射(可选)，默认为物理碎片id映射。
This application also USES he virtual shard option to take care of future database scalability requirements.
该应用程序还使用虚拟碎片选项处理将来的数据库可伸缩性需求。
Your shard strategy should, however, incorporate some means of distributing data evenly among all of your shards.
但是，您的切分策略应该包含将数据均匀分布至所有切分的方法。
In this case, I'm going to shard by race, because I see the domain being organized by runners who belong to RACES.
在本示例中，我将根据比赛进行切分，因为我看到域是根据参加不同比赛的参赛者进行组织的。
If you try to store that data in Shard 2, things will get complicated, and system performance will probably suffer.
如果您尝试将那些数据存储在切分2中，情况就会变得复杂，系统性能也可能受影响。
Database sharding refers to the horizontal partitioning of a database with each individual partition called a shard.
数据库分片是指对数据库进行水平分区，其中每个分区称为一个碎片。
