Abstract
Storage management by a target node for a distributed database includes sending, except the target node, a block query request to n−1 nodes of n nodes of a distributed jointly using a target memory storing some data blocks. N−1 to-be-reclaimed data block sets are received can combined with a to-be-reclaimed data block set maintained by the target node to obtain a combined data block set which is sent to the n−1 nodes. Each of the n−1 nodes removes a data block from the combined data block set and provides an obtained filtered data block set to the target node. The obtained filtered data block set and an n−1 filtered data block set sent by the n−1 nodes as n target data block sets is used by the target node. An overlapping data block of the n target data block sets is determined. The overlapping data block is reclaimed.
