摘要： Techniques for resizing a distributed database are described. A request to resize a distributed database is received. The distributed database stores data organized into one or more rows of one or more tables. Each node of the first plurality of nodes is assigned a portion of the data. A portion of the data assigned to a first node in the first plurality of nodes is selected to be assigned to a second node in a second plurality of nodes. The number of nodes in the first and second plurality of nodes is different, and the first and second plurality of nodes include at least one common node. Metadata of the selected portion of the data is transferred from the first node to the second node. The metadata that includes a location of the selected portion of the data within a provider network.
