摘要： A distributed object is hosted in a distributed system by invoking a global hash function on a generated name for the distributed object. The name for the distributed object is generated with knowledge of the global hash function so that the result of invoking the global hash function upon the name results in the selection of a predetermined node in the distributed system. The predetermined node may be selected based on the affinity of the node to the distributed object for reducing network messaging and communications overhead.

摘要： Disclosed are methods, systems, and computer program products for processing a file which include using a computer system that is programmed for performing a process of receiving the file in response to a request for storing the file, determining whether a database already contains the file, and storing the file in the database if the database does not already contain the file. The process may alternatively include receiving the file in response to a request for storing the file, determining whether a database already contains the file, and storing the file without storing the received file if the database already contains the file. The process may also alternatively include receiving the file in response to a request for storing the file in a database, separating the file into a plurality of portions, and storing the plurality of portions so each of the plurality of portions can be individually accessed.

摘要： For automatic data placement of database data, a plurality of access-tracking data is maintained. The plurality of access-tracking data respectively corresponds to a plurality of data rows that are managed by a database server. While the database server is executing normally, it is automatically determined whether a data row, which is stored in first one or more data blocks, has been recently accessed based on the access-tracking data that corresponds to that data row. After determining that the data row has been recently accessed, the data row is automatically moved from the first one or more data blocks to one or more hot data blocks that are designated for storing those data rows, from the plurality of data rows, that have been recently accessed.
摘要翻译：对于数据库数据的自动数据放置，维持多个访问跟踪数据。多个访问跟踪数据分别对应于由数据库服务器管理的多个数据行。当数据库服务器正常执行时，根据与该数据行相对应的访问跟踪数据，自动确定是否最近访问存储在第一个一个或多个数据块中的数据行。在确定最近访问了数据行之后，数据行被自动从第一个或多个数据块移动到指定用于存储来自多个数据行的那些数据行的一个或多个热数据块，这些数据行具有最近被访问。

摘要： A method and apparatus is provided for optimizing queries received by a database system that relies on an intelligent data storage server to manage storage for the database system. Storing compression units in hybrid columnar format, the storage manager evaluates simple predicates and only returns data blocks containing rows that satisfy those predicates. The returned data blocks are not necessarily stored persistently on disk. That is, the storage manager is not limited to returning disc block images. The hybrid columnar format enables optimizations that provide better performance when processing typical database workloads including both fetching rows by identifier and performing table scans.
摘要翻译：提供了一种方法和装置，用于优化由数据库系统接收的依赖于智能数据存储服务器来管理数据库系统的存储的查询。以混合列格式存储压缩单元，存储管理器将评估简单谓词，并仅返回包含满足这些谓词的行的数据块。返回的数据块不一定存储在磁盘上。也就是说，存储管理器不限于返回盘块图像。混合柱状格式可以实现在处理典型数据库工作负载时提供更好性能的优化，包括通过标识符提取行和执行表扫描。

摘要： Techniques are described herein for automatically selecting the compression techniques to be used on tabular data. A compression analyzer gives users high-level control over the selection process without requiring the user to know details about the specific compression techniques that are available to the compression analyzer. Users are able to specify, for a given set of data, a “balance point” along the spectrum between “maximum performance” and “maximum compression”. The point thus selected is used by the compression analyzer in a variety of ways. For example, in one embodiment, the compression analyzer uses the user-specified balance point to determine which of the available compression techniques qualify as “candidate techniques” for the given set of data. The compression analyzer selects the compression technique to use on a set of data by actually testing the candidate compression techniques against samples from the set of data. After testing the candidate compression techniques against the samples, the resulting compression ratios are compared. The compression technique to use on the set of data is then selected based, in part, on the compression ratios achieved during the compression tests performed on the sample data.
摘要翻译：这里描述了用于自动选择要在表格数据上使用的压缩技术的技术。压缩分析仪为用户提供了对选择过程的高级控制，而不需要用户了解有关压缩分析器可用的特定压缩技术的细节。用户可以为给定的数据集指定沿最大性能和最大压缩之间的平衡点。所选择的点由压缩分析器以各种方式使用。例如，在一个实施例中，压缩分析器使用用户指定的平衡点来确定哪些可用的压缩技术被鉴定为用于给定的一组数据的候选技术。压缩分析仪通过对来自该组数据的样本实际测试候选压缩技术来选择对一组数据使用的压缩技术。在针对样品测试候选压缩技术之后，比较所得到的压缩比。然后，部分地基于在对样本数据执行的压缩测试期间实现的压缩比来选择在该组数据上使用的压缩技术。

摘要： Described herein are compression and processing optimizations by using data transformation techniques. In example embodiments, a byte-wise differential transformation is applied to columnar data represented as a list of length-value pairs to determine a list of delta pairs that is subsequently compressed and stored on persistent storage. A length separation transformation is applied to separate a list of length-value pairs into a length array and a corresponding data value array, where these two arrays are subsequently compressed and stored separately on persistent storage. A native number transformation is applied to a set of number values to remove the lengths stored in the number values, where the transformed set is stored on persistent storage instead of the original set of number values. A native datetime-type transformation is applied to a set of datetime values to generate an encoding that is used to encode the set of datetime values into an encoded set that is stored on persistent storage instead of the original set.
摘要翻译：这里描述的是使用数据变换技术的压缩和处理优化。在示例实施例中，将逐字节差分变换应用于表示为长度值对列表的列数据，以确定随后压缩并存储在持久存储器上的增量对列表。应用长度分离变换将长度值对列表分隔成长度数组和对应的数据值数组，其中这两个数组随后被压缩并分别存储在持久存储器上。原始数字变换被应用于一组数字值以去除存储在数字值中的长度，其中变换的集合存储在永久存储器上而不是原始的数字集合。本机datetime类型转换应用于一组datetime值，以生成用于将datetime值集合编码为存储在永久存储而不是原始集合的编码集中的编码。

摘要： A highly flexible and extensible structure is provided for physically storing tabular data. The structure, is referred to as a compression unit, and may be used to physically store tabular data that logically resides in any type of table-like structure. According to one embodiment, compression units are recursive. Thus, a compression unit may have a “parent” compression unit to which it belongs, and may have one or more “child” compression units that belong to it. In one embodiment, compression units include metadata that indicates how the tabular data is stored within them. The metadata for a compression unit may indicate, for example, whether the data within the compression unit is stored in row-major or column major-format (or some combination thereof), the order of the columns within the compression unit (which may differ from the logical order of the columns dictated by the definition of their logical container), a compression technique for the compression unit, the child compression units (if any), etc.

摘要： Techniques for maintaining a cascading index are provided. In one approach, one or more branch node compression techniques are applied to the main index of a cascading index. In an approach, a Bloom filter is generated and associated with, e.g., a branch node in the main index. The Bloom filter is used to determine whether, without accessing any leaf blocks, a particular key value exists, e.g., in leaf blocks associated with the branch node. In an approach, a new redo record is generated in response to a merge operation between two levels of the cascading index. The new redo record comprises (a) one or more addresses of blocks that are affected by the merge operation, (b) data is that being “pushed down” to a lower level of the cascading index, and (c) one or more addresses of blocks that are written to disk storage as a result of the merge operation.
