| 20120047165 | PROCESS ARCHITECTURE FOR ELASTIC STATEFUL SHARED NOTHING SYSTEM - A database management system implemented in a cloud computing environment. Operational nodes are assigned as controller-nodes, compute-nodes or storage-nodes. The number of operational nodes, and their assignment as compute-nodes or storage-nodes can vary. Queries specify tables, with each such table assigned to a respective group of storage nodes. The number of operational nodes executing a given query may change by (a) changing the compute-nodegroup associated with a connection, or (b) adding or removing nodes from the compute-nodegroup; and/or distributing data from the tables among the nodes in a storage nodegroup. State information is maintained for each client connection, such that steps are executed assuming that the state exists. State changes are recorded during step execution for a given connection, so that subsequent steps from the same connection are executed with the state as left by a prior step, and so that subsequent queries on the same connection are executed with the state as left by the prior query. | 02-23-2012 |
| 20120041976 | MECHANISM FOR CO-LOCATED DATA PLACEMENT IN A PARALLEL ELASTIC DATABASE MANAGEMENT SYSTEM - A database management system implemented in a cloud computing environment. Operational nodes are assigned as groups of controller-nodes, compute-nodes or storage-nodes. Assignments as compute-nodes or storage-nodes vary during execution of queries. Queries specify tables for an associated database operation, and respective storage nodegroup(s). The number of nodes executing a query may change by (a) changing a compute-nodegroup, or (b) adding or removing nodes from a compute nodegroup; and/or distributing data to the storage nodegroup based on a Distribution Method which may be specified by a Distribution Vector (DV) that determines at least where each row is stored. | 02-16-2012 |
| 20120036146 | APPARATUS FOR ELASTIC DATABASE PROCESSING WITH HETEROGENEOUS DATA - A database management system implemented in a cloud computing environment. Operational nodes are assigned as groups of controller-nodes, compute-nodes or storage-nodes. Queries specify one or more tables for an associated database operation, with each table being assigned to respective storage nodegroup(s). The number of nodes executing a given query may change, by (a) changing the compute-nodes associated with a connection, or (b) adding or removing nodes associated with a connection; and/or distributing data to a storage nodegroup based on a Distribution Method which may be either data dependent or data independent. A controller node further executes a Dynamic Query Planner (DQP) process that develops a query plan. | 02-09-2012 |
