摘要： 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.

摘要： A system that implements a scaleable data storage service may maintain tables in a non-relational data store on behalf of service clients. Each table may include multiple items. Each item may include one or more attributes, each containing a name-value pair. The system may provide an API through which clients can query tables maintained by the service. Items may be partitioned and indexed in a table according to a simple or composite primary key contained in all items in the table. A composite primary key may include a hash key attribute, and a range key attribute. The range key attribute may be usable to order items having the same hash key attribute value, and to partition them dependent on a range of range key attribute values. A query request may specify a logical or mathematical expression dependent on range key attribute values and may be directed to multiple partitions.

摘要： A method and system is provided for maintaining customer data in a data store system utilizing a scalable partitioning framework. More specifically, the data store of a customer service system is partitioned (divided) into multiple partitions by a partitionable key of customer data so that each partition owns a subset of the customer data. By maintaining several partitions that store a subset of the customer data exclusive to each other, blackout or brownout problems can be local to one partition and, thus, the availability for the entire system will be increased. Moreover, a set of partitionable keys, a minimal unit to be moved between partitions, is grouped and associated with a partition. By eliminating direct dependencies between the partitions and the partitionable keys, the system can have great flexibility with regard to migrating customer data between partitions and adding a new partition.

摘要翻译： 提供了一种方法和系统，用于使用可伸缩的分区框架将客户数据维护在数据存储系统中。 更具体地，客户服务系统的数据存储通过客户数据的可分割密钥被分割（分割）成多个分区，使得每个分区拥有客户数据的子集。 通过维护存储彼此独占的客户数据子集的多个分区，停电或掉电问题可以是一个分区的本地，因此整个系统的可用性将会增加。 此外，一组可分区密钥（在分区之间移动的最小单位）被分组并与分区相关联。 通过消除分区和可分区密钥之间的直接依赖关系，系统可以在分区之间迁移客户数据并添加新分区方面具有很大的灵活性。

摘要： An analyzer/classifier/synthesizer/prioritizing tool for data comprises use of an admissible geometrization process with data transformed and partitioned by an input process into one or more input matrices and one or more partition classes and one or more scale groups. The data to be analyzed/classified/synthesized/prioritized is processed by an admissible geometrization technique such as 2-partition modified individual differences multidimensional scaling (2p-IDMDS) to produce at least a measure of geometric fit. Using the measure of geometric fit and possibly other 2p-IDMDS output, a back end process analyzes, synthesizes, classifies, and prioritizes data through patterns, structure, and relations within the data.

摘要： A database management system has a plurality of database servers and data can be transferred between them by partitioning a data area into small areas and altering allocation of the small areas to the database servers. After altering the configuration, there occurs degradation in processing speed that accompanies re-creation of the index. If this problem is solved by using conventional techniques, noticeable degradation in processing speed will occur to a specific query at the time of a steady state operation. Accordingly, an index created for each of the small areas and an index to all of the small areas are allocated to the database server and used in combination.

摘要： When operating a database management system that consists of a plurality of database servers and enables the database servers to transfer data between them by partitioning a data area into small areas and altering allocation of the small areas to the database servers, after altering the configuration, there occurs degradation in processing speed that accompanies re-creation of the index. If this problem is solved by using the conventional technique, noticeable degradation in processing speed will occur to a specific query at the time of a steady state operation. When operating the database management system that consists of the plurality of database servers and enables the database servers to transfer data between them by partitioning the database area into small areas and altering the allocation of the small areas to the database server, an index created for each of the small areas and an index to all the small areas allocated to the database server are used in combination.
