    • A mechanism for handling transaction messages in asynchronous data replication in a database system, in which the database system includes a source node and a target node, and each transaction message has information concerning a row change to a table copy at the source node. The mechanism determines whether a first transaction message has a dependency on a preceding non-completed transaction message. Responsive to the first transaction message having a dependency on the preceding non-completed transaction, the mechanism holds the first transaction message, completes the preceding non-completed transaction message including applying the row change associated with the preceding non-completed transaction message to the table copy at the target node, and responsive to completing the preceding non-completed transaction message, releases the first transaction message and applying the row change associated with the first transaction message to the table copy at the target node.
    • 用于在数据库系统中处理异步数据复制中的事务消息的机制,其中数据库系统包括源节点和目标节点,并且每个事务消息具有关于在源节点处的表副本的行更改的信息。 该机制确定第一事务消息是否具有对先前未完成的事务消息的依赖性。 响应于对先前未完成的事务具有依赖性的第一交易消息,该机制保持第一交易消息,完成前述未完成的交易消息,包括将与先前未完成的交易消息相关联的行变更应用于表 在目标节点处的副本,并且响应于完成上述未完成的交易消息,释放第一交易消息并将与第一交易消息相关联的行变更应用于目标节点处的表副本。

    • 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。
