Abstract:
A method for data redistribution of a job data in a first datanode (DN) to at least one additional DN in a Massively Parallel Processing (MPP) Database (DB) is provided. The method includes recording a snapshot of the job data, creating a first data portion in the first DN and a redistribution data portion in the first DN, collecting changes to a job data copy stored in a temporary table, and initiating transfer of the redistribution data portion to the at least one additional DN.
