Abstract
There is provided a method and apparatus for free space management in a distributed database. Each datanode of the database is assigned a free space map to manage free space. When a datanode requires additional storage space, a new free space map may be assigned to the datanode, a free space map of a different datanode may be shared with the datanode, or a free space map of a different datanode may be reassigned to the datanode. A background process may be used to recycle inactive free space maps.
