    • A data item is retrieved from a data store in a data processing system. The data processing system comprises an index, which at least partially indexes the data store, and also a partiality definition store. The partiality definition store indicates a part of the data store which is referenced by the partial index. A request is received for a data item from the data store and responsive to determining that the requested data item is not referenced by the partial index, the data store is searched by using the partiality definition store to avoid searching a part of the data store which is known to be indexed.
    • 从数据处理系统中的数据存储中检索数据项。 数据处理系统包括至少部分地索引数据存储的索引,以及偏倚定义存储。 偏好定义存储指示由部分索引引用的数据存储的一部分。 接收到来自数据存储器的数据项的请求,并响应于确定所请求的数据项未被部分索引引用,通过使用偏好定义存储来搜索数据存储,以避免搜索数据存储的一部分 已知索引。

    • There is disclosed a method for use in managing databases in data storage systems comprising a plurality of nodes. A request is received to provision storage for a specified application intending to use a database. Based on application-awareness, the storage system is provisioned for storing the database in response to receiving the request. Database tables are distributed across the nodes based on a forecasted first I/O profile between application and database. Information is captured in connection with the activity between the application and database. A second I/O profile is determined based on the captured information. The second I/O profile is an actual in-running I/O profile between application and database. The first I/O profile and second I/O profile are compared. The database tables are re-organized on the nodes based on the comparison identifying a discrepancy between first and second I/O profiles such that storage system is rebalanced.
    • 公开了一种用于在包括多个节点的数据存储系统中管理数据库的方法。 接收到一个请求,以便为打算使用数据库的指定应用程序提供存储。 基于应用程序感知,存储系统被提供用于响应于接收到请求而存储数据库。 数据库表根据应用程序和数据库之间预测的第一个I / O配置文件分布在节点之间。 与应用程序和数据库之间的活动相关联地捕获信息。 基于捕获的信息确定第二I / O配置文件。 第二个I / O配置文件是应用程序和数据库之间的实际正在运行的I / O配置文件。 比较第一个I / O配置文件和第二个I / O配置文件。 基于识别第一和第二I / O配置文件之间的差异的比较,数据库表在节点上重新组织,使得存储系统被重新平衡。

    • Methods, a system, and a program product for use in managing data storage is disclosed. In an embodiment, a method, system, and program product comprises receiving content via an object based storage interface to a data storage system; generating a database insert operation for an object derived from the content, the object having a generated object identifier; and using the database entry operation, storing data associated with the object in a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.In another embodiment, a method comprises receiving a delete command for an object via an object based interface to a data storage system; generating a database delete operation for the object based on the delete command; and using the database delete operation, deleting data associated with the object in a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.In yet another embodiment, a method comprises receiving a search command via an object based interface to a data storage system; generating a database query based on the search command; and using the database query, querying a shared-nothing database located within the data storage system, wherein the shared-nothing database is enabled to perform parallel processing across multiple independent nodes.
    • 公开了用于管理数据存储的方法,系统和程序产品。 在一个实施例中,方法,系统和程序产品包括经由基于对象的存储接口接收内容到数据存储系统; 为从所述内容导出的对象生成数据库插入操作,所述对象具有生成的对象标识符; 以及使用所述数据库输入操作,将与所述对象相关联的数据存储在位于所述数据存储系统内的无共享数据库中,其中所述无共享数据库能够跨多个独立节点执行并行处理。 在另一个实施例中,一种方法包括通过基于对象的接口向数据存储系统接收对象的删除命令; 基于删除命令生成对象的数据库删除操作; 以及使用所述数据库删除操作,删除位于所述数据存储系统内的无共享数据库中与所述对象相关联的数据,其中所述无共享数据库能够跨多个独立节点执行并行处理。 在另一个实施例中,一种方法包括经由基于对象的接口向数据存储系统接收搜索命令; 基于搜索命令生成数据库查询; 以及使用数据库查询,查询位于数据存储系统内的无共享数据库,其中无共享数据库能够跨多个独立节点执行并行处理。

    • In one embodiment of the invention, a utility may be installed (e.g., by a system administrator) on a storage system. The utility may read content units on the storage system that are stored in one data format, and convert the content units to a second data format. In one embodiment, in response to a read request for a content unit, a data format in which to return the content unit may be selected and the content unit may be returned in that data format. In another embodiment, mapping information may be created that specifies in which data format a content unit should be returned in response to a request for the content unit. The mapping information may be stored either on the storage system that stores the content unit, the computer requesting access to the content unit, or any other computer or device in the computer system.
