Abstract
In an embodiment of the present invention, a checkpoint is received, the checkpoint indicating at least one source position of unprocessed object(s) of a plurality of objects on at least one source shard in a database system. In response to detecting a shard change related to the checkpoint to the at least one source shard, the shard change resulting in that the at least one source shard is updated to at least one destination shard, a mapping view is generated for representing position change of the unprocessed object(s) related to the shard change. An updated checkpoint is determined for indicating the at least one destination position of the unprocessed object(s) of the plurality of objects on at least one destination shard in the database system based on the mapping view. With these embodiments, the checkpoint may be managed in a more effective way.
