Abstract
Architecture that provides the capability to automatically (e.g., dynamically) reorganize (repartition) an existing partition by dividing (splitting) or recombining (merging) logical databases. This reorganization can be performed to logical databases belonging to the same customer, and based on the partitioning of the tables in these databases. This can include not only splitting secondary replicas of a partition or merging secondary replicas of the partition, but also splitting off secondary replicas of the partition to create a new partition and merging two partitions into one partition. Moreover, these operations can occur while the logical databases are accepting workload (online).
