摘要： Techniques are provided for using an intermediate cache to provide some of the items involved in a scan operation, while other items involved in the scan operation are provided from primary storage. Techniques are also provided for determining whether to service an I/O request for an item with a copy of the item that resides in the intermediate cache based on factors such as a) an identity of the user for whom the I/O request was submitted, b) an identity of a service that submitted the I/O request, c) an indication of a consumer group to which the I/O request maps, d) whether the I/O request is associated with an offloaded filter provided by the database server to the storage system, or e) whether the intermediate cache is overloaded. Techniques are also provided for determining whether to store items in an intermediate cache in response to the items being retrieved, based on logical characteristics associated with the requests that retrieve the items.

摘要： A method for starting up a database system, comprising allocating memory spaces for three buffers; initializing two of the buffers; partially initializing the third buffer where the third buffer is larger than the other two; instructing the memory manager to initialize the remainder of the third buffer in the background process; performing recovery operations; and opening the database system for use. The database is operated in an open phase while the remainder of the third buffer is initialized in the background and ran in parallel to the recovery operation that may extend beyond the completion of opening the database. Thus opening the database prior to completion of full initialization and initializing the third buffer in the background improves the startup time of the database which becomes significant when the size of the third buffer is very large (e.g., 500 GB+).

摘要： Processing resources at a storage system for a database server are utilized to perform aspects of a join operation that would conventionally be performed by the database server. When requesting a range of data units from a storage system, the database server includes join metadata describing aspects of the join operation for which the data is being requested. The join metadata may be, for instance, a bloom filter. The storage system reads the requested data from disk as normal. However, prior to sending the requested data back to the storage system, the storage system analyzes the raw data based on the join metadata, removing a certain amount of data that is guaranteed to be irrelevant to the join operation. The storage system then returns filtered data to the database server. The database system thereby avoids the unnecessary transfer of certain data between the storage system and the database server.
摘要翻译：利用用于数据库服务器的存储系统处理资源来执行通常由数据库服务器执行的连接操作的方面。当从存储系统请求一系列数据单元时，数据库服务器包括描述正在请求数据的连接操作的方面的连接元数据。连接元数据可以是例如布隆过滤器。存储系统正常从磁盘读取所请求的数据。然而，在将所请求的数据发送回存储系统之前，存储系统基于连接元数据分析原始数据，去除与加入操作无关的一定量的数据。存储系统然后将过滤的数据返回到数据库服务器。因此，数据库系统避免了存储系统和数据库服务器之间的某些数据的不必要的传送。

摘要： Allocation of memory is optimized across multiple pools of memory, based on minimizing the time it takes to successfully retrieve a given data item from each of the multiple pools. First data is generated that indicates a hit rate per pool size for each of multiple memory pools. In an embodiment, the generating step includes continuously monitoring attempts to access, or retrieve a data item from, each of the memory pools. The first data is converted to second data that accounts for a cost of a miss with respect to each of the memory pools. In an embodiment, the second data accounts for the cost of a miss in terms of time. How much of the memory to allocate to each of the memory pools is determined, based on the second data. In an embodiment, the steps of converting and determining are automatically performed, on a periodic basis.

摘要： An automated method of rapidly producing customized 3D graphics images in which various user images and video are merged into 3D computer graphics scenes, producing hybrid images that appear to have been created by a computationally intensive 3D rendering process, but which in fact have been created by a much less computationally intensive series of 2D image operations. To do this, a 3D graphics computer model is rendered into a 3D graphics image using a customized renderer designed to automatically report on some of the renderer's intermediate rendering operations, and store this intermediate data in the form of metafilm. User images and video may then be automatically combined with the metafilm, producing a 3D rendered quality final image with orders of magnitude fewer computing operations. The process can be used to inexpensively introduce user content into sophisticated images and videos suitable for many internet, advertising, cell phone, and other applications.
