摘要： In one embodiment, a database server registers one or more functions included in a user-defined index that includes one or more auxiliary properties. The one or more functions are operable to generate index entries of the user-defined index for the one or more auxiliary properties. The one or more auxiliary properties are different than, and in addition to, a primary property of the user-defined index that provides for evaluating a query operator. The database server receives a first statement that defines the user-defined index, where the first statement includes one or more parameters that define the one or more auxiliary properties. The database server invokes the one or more functions in response to the first statement, where the one or more functions when invoked generate and store the index entries of the user-defined index according to the one or more parameters that define the one or more auxiliary properties.

摘要： A method, system, and computer program product provides improved performance for rebuild of user-defined indexes during partition maintenance operations (partition split, merge, and move). A method of maintaining a index of a partitioned database table comprises performing a partition maintenance operation on the partitioned database table wherein a plurality of rows of the partitioned database table are moved from one partition to another, storing mapping information for at least some of the plurality of moved rows, including an old mapping for each of the moved rows and a corresponding new mapping for each of the moved rows, and when rebuilding the index, replacing an old mapping in the index for each of the plurality of moved rows with the corresponding stored new mapping for each of the plurality of moved rows.

摘要： Systems, methodologies, media, and other embodiments associated with supporting materialized views with user-defined aggregates are described. One example system includes logic for exposing a set of interface actions to support a user-defined aggregate in a materialized view associated with a base table. The materialized view may store both the user-defined aggregate and a user-defined aggregate context that facilitates logically connecting the user-defined aggregate to the base table. The example system may also include logic for supporting the user-defined aggregate. The support may be based on the set of interface actions. Example systems and methods may, therefore, facilitate incremental updating of the materialized view and/or rewriting a query to access the materialized view.

摘要： Systems, methodologies, media, and other embodiments associated with supporting queries with hard time constraints are described. One exemplary system embodiment includes logic for accepting a query having a hard time constraint. The example system may also include logic for selectively rewriting the query having the hard time constraint into a query having a row limitation or a sample percentage limitation. In one example, the row limitation or sample percentage limitation are computed by repetitively comparing an estimated query execution time to the hard time constraint. The example system may also include logic for establishing a timer(s) associated with the rewritten query.

摘要： Techniques are described for generating histograms for a multidimensional space. In the presence of large spatial objects, fuzzy splitting techniques are utilized to recursively divide the multidimensional space into partitions, where a single spatial object may belong to multiple partitions. Large spatial objects are essentially broken down into smaller objects that may allow for more efficient partitioning of the multidimensional space. A count of spatial objects in each partition yields a spatial histogram. A spatial object that belongs to multiple partitions may have a weighted count for each of the multiple partitions, based on the extent to which the spatial object overlaps with each partition. Thus, an object that is split among a handful of partitions will only contribute a fraction of a count to each partition. Small partitions having relatively few objects are avoided by refusing to subdivide a partition whose members drop below a threshold number.
摘要翻译：描述了用于生成多维空间的直方图的技术。在存在大空间物体的情况下，使用模糊分割技术将多维空间递归地划分成分区，其中单个空间对象可能属于多个分区。大的空间对象基本上被分解成更小的对象，这可以允许对多维空间进行更有效的划分。每个分区中的空间对象的计数产生空间直方图。基于空间对象与每个分区重叠的程度，属于多个分区的空间对象可以具有针对多个分区中的每一个的加权计数。因此，在少数分区之间分割的对象只会为每个分区贡献一部分计数。通过拒绝细分成员下降到阈值以下的分区来避免具有相对较少对象的小分区。
