Abstract
Techniques are disclosed relating to migrating database extents between physical storage nodes. A database system stores current and new assignment metadata mapping virtual groupings of database extents physical storage nodes, the new assignment metadata reflecting a data migration of extents between the plurality of physical storage nodes. During the migration, the database system receives 1) read requests, which it responds to by reading data from a first physical storage node identified using the current assignment metadata and 2) write requests, which it responds to by writing data to a second physical storage node identified using the new assignment metadata. Upon the migration being complete, the system identifies physical storage nodes accessed by subsequent read and write requests using the new assignment metadata.
