Abstract: A system that implements a scalable data storage service may maintain tables in a non-relational data store on behalf of clients. The system may provide a Web services interface through which service requests are received, and an API usable to request that a table be created, deleted, or described; that an item be stored, retrieved, deleted, or its attributes modified; or that a table be queried (or scanned) with filtered items and/or their attributes returned. An asynchronous workflow may be invoked to create or delete a table. Items stored in tables may be partitioned and indexed using a simple or composite primary key. The system may not impose pre-defined limits on table size, and may employ a flexible schema. The service may provide a best-effort or committed throughput model. The system may automatically scale and/or re-partition tables in response to detecting workload changes, node failures, or other conditions or anomalies.

Abstract: A system that implements a scaleable data storage service may maintain tables in a non-relational data store on behalf of clients. Each table may include multiple items. Each item may include one or more attributes, each containing a name-value pair. Attribute values may be scalars or sets of numbers or strings. The system may provide an API usable to request that values of one or more of an item's attributes be updated. An update request may be conditional on expected values of one or more item attributes (e.g., the same or different item attributes). In response to a request to update the values of one or more item attributes, the previous values and/or updated values may be optionally returned for the updated item attributes or for all attributes of an item targeted by an update request. Items stored in tables may be indexed using a simple or composite primary key.

Abstract translation: 实现可扩展数据存储服务的系统可以代表客户端在非关系数据存储中维护表。 每个表可以包括多个项目。 每个项目可以包括一个或多个属性，每个属性包含名称 - 值对。 属性值可以是标量或数字或字符串集合。 系统可以提供可用于请求更新项目属性中的一个或多个的值的API。 更新请求可以以一个或多个项目属性（例如，相同或不同的项目属性）的预期值为条件。 响应于更新一个或多个项目属性的值的请求，可以可选地为更新的项目属性或由更新请求定向的项目的所有属性返回先前值和/或更新的值。 存储在表中的项目可以使用简单或复合主键进行索引。
