Sharding is a particularly cost-effective decision for organizations tied to a relational infrastructure that cannot continue to upgrade hardware to meet the need for massively scalable data storage.
切分对于绑定于关系基础架构、无法继续升级硬件以满足大量可伸缩数据存储要求的组织来说是一个非常成本高效的决策。
Sharding also conceivably improves reliability, because even if one shard unexpectedly fails, others are still able to serve data.
切分还可以改善可靠性，因为即便一个切分意外失效，其他切分仍然可以服务数据。
In the Microsoft sharding pattern a "sharding key" is used to map data to specific shards which is the primary key in one of the data entities.
在微软的分片模式中，“分片键”用于将数据映射到特定的分片上，后者就是一个数据实体的主键。
