Title:
DYNAMIC COMPUTATION NODE GROUPING WITH COST BASED OPTIMIZATION FOR MASSIVELY PARALLEL PROCESSING
Document Type and Number:
WIPO Patent Application WO/2018/103520
Kind Code:
A1
Abstract:
A massively parallel processing shared nothing relational database management system includes a plurality of storages assigned to a plurality of compute nodes. The system comprises a non-transitory memory having instructions and one or more processors in communication with the memory. The one or more processors execute the instructions to store a set of data in a first set of storages in the plurality of storages. The first set of data is hashed into a repartitioned set of data. The first set of storages is reassigned to a second set of compute nodes in the plurality of compute nodes. The repartitioned set of data is distributed to the second set of compute nodes and a database operation is performed on the repartitioned set of data by the second set of compute nodes.
