发明名称 METHOD FOR MAINTAINING PARALLELISM IN DATABASE PROCESSING USING RECORD IDENTIFIER SUBSTITUTION ASSIGNMENT
摘要 In one implementation, a method for sustaining database processing parallelism of one or more parallelized processes to build one or more index pages using pseudo record identifiers (PRIDs) is disclosed. The method comprises generating one or more PRIDs for one or more respective internal record formats (IRFs), inserting said generated PRIDs into a respective index key, generating a relational index of the PRID and a predetermined record identifier (RID) respectively determined in relation to said IRF, and building one or more index pages in relation to the relational index by comparing said RID and said PRID for their respective IRF in said relational index, and determining which one of said RID or said PRID to insert into said index page.
