BALANCED PARTITION PLACEMENT IN DISTRIBUTED DATABASES |
| 摘要 |
For balanced partition placement in a distributed database, a first node in a set of nodes is identified, at an application executing using a processor and a memory, for a first primary partition of the distributed database, such that the primary partition and a first replica corresponding to the primary partition reside on different nodes in the set of nodes. A second node in the set of nodes is selected to place the first replica such that the second node does not include a second replica of a second primary partition, wherein the first primary partition and the second primary partition are co-resident on the first node. The first primary partition is placed on the first node and the first replica is placed on the second node. |

1. A method for balanced partition placement in a distributed database, the method comprising:
identifying, at an application executing using a processor and a memory, a first node in a set of nodes for a first primary partition of the distributed database, such that the primary partition and a first replica corresponding to the primary partition reside on different nodes in the set of nodes; selecting a second node in the set of nodes to place the first replica such that the second node does not include a second replica of a second primary partition, wherein the first primary partition and the second primary partition are co-resident on the first node; and placing the first primary partition on the first node and the first replica on the second node. |
