摘要： Each of a plurality of data items is stored in a table data structure. A row identifier and column identifier are associated with each respective data item, and each respective item is stored at a logical location in the table data structure specified by its row identifier and column identifier. A plurality of data items is stored in a cell of the table data structure, and a timestamp is associated with each of the plurality of data items stored in the cell. Each of the data items stored in the cell has the same row identifier, the same column identifier, and a distinct timestamp. In some embodiments, each row identifier is a string of arbitrary length and arbitrary value. Similarly, in some embodiments each column identifier is a string of arbitrary length and arbitrary value.

摘要： Each of a plurality of data items is stored in a table data structure. The table structure includes a plurality of columns. Each of the columns is associated with one of a plurality of locality groups. Each locality group is stored as one or more corresponding locality group files that include the data items in the columns associated with the respective locality group. In some embodiments, the columns of the table data structure may be grouped into groups of columns and each group of columns is associated with one of a plurality of locality groups. Each locality group is stored as one or more corresponding locality group files that include the data items in the group of columns associated with the respective locality group.

摘要： When a search query is received, a plurality of partition indexes are searched using the set of search terms in the search query. Each partition index corresponds to a partition of a document index. The search of each respective partition index identifies a subset of a plurality of document index sub-partitions corresponding to the respective partition index. Next, the search query is executed by only those document index sub-partitions identified by the subsets, thereby identifying documents that satisfy the search query. By using the partition index to reduce the number of document index sub-partitions searched while executing a search query, the execution of the search query is made more efficient.
摘要翻译： 当接收到搜索查询时，使用搜索查询中的搜索项集来搜索多个分区索引。 每个分区索引对应于文档索引的分区。 每个相应分区索引的搜索标识对应于相应分区索引的多个文档索引子分区的子集。 接下来，搜索查询仅由由子集标识的那些文档索引子分区执行，从而识别满足搜索查询的文档。 通过使用分区索引来减少在执行搜索查询时搜索的文档索引子分区的数量，使得搜索查询的执行更有效。

摘要： Once a search query is received from a user, a standard index is searched based on the search query. The standard index forms part of a set of replicated standard indexes having multiple instances of the standard index. A signal is then determined based on the search of the standard index. When the received signal meets predefined criteria, an extended index is searched. The extended index forms part of a set of extended indexes having at least one instance of the extended index. There are fewer instances of the extended index than instances of the standard index. Extended search results are then obtained from the extended index and at least a portion of the extended search results is transmitted towards a user.
摘要翻译： 一旦从用户接收到搜索查询，就会根据搜索查询来搜索标准索引。 标准索引构成了具有标准索引的多个实例的一组复制标准索引的一部分。 然后基于标准索引的搜索来确定信号。 当接收到的信号满足预定标准时，搜索扩展索引。 扩展索引构成一组具有扩展索引的至少一个实例的扩展索引的一部分。 扩展索引的实例少于标准索引的实例。 然后从扩展索引获得扩展搜索结果，并向用户发送扩展搜索结果的至少一部分。

摘要： When searching a document database in response to a search query, a determination is made as to whether a query result corresponding to the search query is stored in a cache. When the query result is stored in the cache, a reuse count for the search query is accessed. When predefined conditions are satisfied, such as the reuse count being larger than a predetermined threshold count, an improved search result is generated in accordance with a first set of predetermined searching criteria, and at least a subset of the improved search result is returned.

摘要： A system and method for providing load balanced processing is described. One or more files selected from a set of files are logically duplicated. At least one file and at least one logically duplicated file, is stored at one of a plurality of servers as specified in a load balancing layout. Execution of each operation in an operation stream is scheduled on the server storing at least one staged file required by the operation.

摘要： Short duration micro-sleep or nap periods reduce the power consumption of a computing device. In use, the computing device determines a first duration to a next expected event in the computing device, and compares the first duration to a minimum micro-sleep duration. If the first duration is greater than or equal to the minimum duration, then the processor enters a processor sleep state for a sleep duration. The processor then wakes up and returns to a running state at the end of the sleep duration and before the next expected event. This permits the use of a low-power sleep state while giving the appearance that the computing device is functional. As an additional requirement before entering micro-sleep, the current or recent processor load may be evaluated to determine whether a micro-sleep interval is appropriate.
摘要翻译： 短时间的微睡眠或睡眠时间可以减少计算设备的功耗。 在使用中，计算设备确定计算设备中的下一预期事件的第一持续时间，并将第一持续时间与最小微睡眠持续时间进行比较。 如果第一持续时间大于或等于最小持续时间，则处理器进入处理器休眠状态以进行睡眠持续时间。 然后处理器唤醒并在睡眠持续时间结束时和下一个预期事件之前返回到运行状态。 这允许使用低功率睡眠状态，同时给出计算设备的功能的外观。 作为进入微睡眠之前的额外要求，可以评估当前或最近的处理器负载以确定微睡眠间隔是否合适。
