PIPELINED RE-SHUFFLING FOR DISTRIBUTED COLUMN STORE
Abstract:
A method of pipelining re-shuffled data of a distributed column oriented relational database management system (RDBMS). A request is received from a consumer process that requires RDBMS column data to be shuffled in a specific order according to an order that each of a plurality of columns will be used by the consumer process. For each of the plurality of columns, the method re-shuffles the RDBMS column data according to the specific order to form re-shuffled RDBMS column data, and sends the re-shuffled RDBMS column data to the consumer process.
