A distributed database system providing data and space management methodology. In one embodiment, for example, a method for transferring a data structure in cache at a first database server to a second database server in a distributed database system comprises steps of: determining a first database server having a data structure in cache in response to a request for the data structure from a second database server, the request including a request for a lock on the data structure; providing the request for the data structure to the first database server; in response, sending the data structure from the first database server to the second database server; and receiving and using the data structure at the second database server without waiting for the lock request to be explicitly granted.
