    摘要： An index scan processor and method to perform concurrent scans of stored indexed data. An indexed data scanner performs a first scan of stored data by sequentially scanning through an index data structure and maintains, over a duration of the first scan, a first scan current scan location within the index data structure that indicates a currently accessed record within the stored data structure for the first scan. A scan manager accepts a request for a second scan of the stored data, determines, during the performing the first scan, a starting index scan location within the index data structure for the second scan that is sufficiently near the first scan current index scan location to cause records indicated by the starting location index to be stored within a buffer due to the performing the first scan, and starts the second scan at the starting location and proceeding to the second end key.

    摘要： Disclosed are a method, information processing system, and computer readable medium for scanning a storage medium table. The method includes retrieving location information associated with at least one other storage medium table scan. A storage medium table scan is started at a location within a storage medium table based on at least a location of the one other storage medium table scan. A weight is assigned to at least one storage medium block based on at least a current scanning location within the storage medium table relative to the location of the one other table scan. The method determines if a distance between the current scanning location and the location of the one other table scan is greater than a first given threshold. A current scanning operation is delayed, in response to the distance being greater than the given threshold, until the distance is below a second given threshold.

    摘要： A method and processor to determine distances between multiple index driven scan operations. A first anchor index entry is identified during a first index scan and stored. A first number of index entries between the first anchor index entry and a first index scan location being processed by a first index scan is determined based on information maintained external to an index structure. A determination is made of second number of index entries between the first anchor index entry and a second index scan location being processed by a second index scan executing concurrently with the first index scan based on information maintained external to the index structure. A distance between the first index scan location and the second index scan location is calculated as equal to a difference between the first number of index entries and the second number of index entries.
