摘要： Techniques for collecting statistics of column data or R-Tree indexes are provided. A distributed database system includes a plurality of processing nodes controlling portions of spatial data. The nodes are instructed to create minimum bounding rectangles (MBR's) for their spatial data or R-Trees. The individual MBR's are merged and reformatted into a grid of equally sized cells. Each processing node is provided a copy of the grid to update based on statistics of each processing node's spatial data for a target table. The updated grids are then merged into a single grid and used by an optimizer to evaluate queries before the queries are executed.

摘要： Techniques for mapping a virtual R-Tree to an extensible-hash based file system for databases are provided. Spatial data is identified within an existing file system, which stores data for a database. Rows of the spatial data are organized into collections; each collection represents a virtual block. The virtual blocks are used to form an R-Tree spatial index that overlays an existing index for the database on the existing file system. Each row within its particular virtual block includes a pointer to its native storage location within the existing file system.

摘要： Embodiments of the present invention provide for batch and incremental loading of data into a database. In the present invention, the loader infrastructure utilizes machine code database instructions and hardware acceleration to parallelize the load operations with the I/O operations. A large, hardware accelerator memory is used as staging cache for the load process. The load process also comprises an index profiling phase that enables balanced partitioning of the created indexes to allow for pipelined load. The online incremental loading process may also be performed while serving queries.

摘要： Techniques are presented for skew exception detection within a parallel processing environment. A potential exception is detected when a highest load of a processor within the parallel processing environment exceeds an average load within the parallel processing environment by a given threshold. The potential exception can become a legitimate exception when it exists for a qualified period or time or when it exists and no qualified period of time is noted. In an embodiment, checks for the potential exception occur and are wholly contained within a given configurable interval.
