    摘要： An improved architecture is provided which enables significant convergence of the components of a system to implement virtualization. The infrastructure is VM-aware, and permits scaled out converged storage provisioning to allow storage on a per-VM basis, while identifying I/O coming from each VM. The current approach can scale out from a few nodes to a large number of nodes. In addition, the inventive approach has ground-up integration with all types of storage, including solid-state drives. The architecture of the invention provides high availability against any type of failure, including disk or node failures. In addition, the invention provides high performance by making I/O access local, leveraging solid-state drives and employing a series of patent-pending performance optimizations.

    摘要： Techniques are provided for processing a CREATE INDEX statement that avoids one or more locks on the underlying table. The processing of such a statement may be divided into a build phase and a cooperation phase. During the build phase, a journal table is created and published. A snapshot of the table is obtained after the last DML transaction (that was pending at the time the journal table was published) commits. The index is built based on the state of the table as of the snapshot. Any changes to the table while the index is built are recorded in the journal table. During the cooperation phase, the index is partially published. A subsequent DML statement determines whether any changes in the journal table affect the same data as the subsequent DML statement. If so, then those changes are applied to the index followed by the subsequent DML statement.

    摘要： Performing an operation directly on data stored in a database table provides for avoiding generation and processing of SQL statements. A Data Layer interface, comprising a set of APIs, allows internal database server components to call directly to the Data Layer for making fast row changes to a table. According to an embodiment, before making any row change to a table through this Data Layer interface, a shared state data structure is created to hold the metadata about the table. A single shared state can be used for all DML changes to a particular table regardless of what columns are updated or inserted during each DML operation. When a process needs to change a row, the process uses a mutable state based on the shared state of the table.

    摘要翻译： 直接对存储在数据库表中的数据执行操作可避免SQL语句的生成和处理。 包含一组API的数据层接口允许内部数据库服务器组件直接调用数据层，以便对表进行快速行更改。 根据实施例，在通过该数据层接口对表进行任何行更改之前，创建共享状态数据结构以保存关于表的元数据。 无论在每个DML操作期间更新或插入哪些列，单个共享状态可用于对特定表的所有DML更改。 当进程需要更改一行时，进程将使用基于表的共享状态的可变状态。

    摘要： A method of processing data from a file includes obtaining a first portion of the file, encrypting the first portion of the file to create a first encrypted portion, obtaining a second portion of the file, encrypting the second portion of the file to create a second encrypted portion, and storing the first and second encrypted portions such that each of the first and the second encrypted portions can be individually accessed. A method of processing data from a file includes receiving a request to access a first portion of the file, wherein data in the first portion of the file is encrypted, and data in a second portion of the file is encrypted, and decrypting the data in the first portion, and not the data in the second portion.

    摘要： A partial reverse key index is described, which allows distributed contention as resources vie to insert data into an index as well as allows range scans to be performed on the index. To do so, before an index entry for a key value is inserted into an index, the key value is transformed using a transformation operation that affects a subset of the order of the key value. The index entry is then inserted based on the transformed key value. Because the transformation operation affects the order of the key value, the transformed values associated with two consecutive key values will not necessarily be consecutive. Therefore, the index entries associated with the consecutive key values may be inserted into unrelated portions of the index.

    摘要翻译： 描述了部分反向密钥索引，其允许分布式争用作为将数据插入到索引中的资源，并且允许在索引上执行范围扫描。 为此，在将键值的索引条目插入索引之前，将使用影响键值顺序子集的转换操作来转换键值。 然后基于转换的键值插入索引条目。 由于转换操作影响键值的顺序，与两个连续的键值相关联的变换值不一定是连续的。 因此，可以将与连续键值相关联的索引条目插入索引的无关部分。
