  • Increasing distributed database capacity
    Patent number: 9576019
    Abstract: Disclosed are various embodiments for increasing distributed database capacity by adding new nodes while minimizing downtime. A database is partitioned among multiple nodes in a cluster. Each node stores a respective portion of the database. The portions of the database are replicated to corresponding physical standbys. For each portion, a first portion is mapped to an existing node, while a remaining portion is mapped to a physical standby. The cluster is updated to include the physical standbys as additional nodes among which the database is partitioned.
    Type: Grant
