Abstract
Methods, systems, and computer-readable media for renaming a database table with minimized application downtime are disclosed. A database receives a table rename request for a table having a first table name. Routing metadata comprises a mapping of the first table name to a table identifier and a mapping of the table identifier to one or more partitions. The table rename request indicates a second table name. The database generates updated routing metadata responsive to the table rename request. The updated routing metadata comprises a mapping of the second table name to the table identifier and the mapping of the table identifier to the one or more partitions. The database receives, from a client application, one or more access requests indicating the second table name. The database routes the one or more access requests to the one or more partitions based at least in part on the updated routing metadata.
