Abstract
Provided is a method for recovering a block in a database system. Provided is a method for recovering a database block, including: deciding one or more recovery candidate blocks by reading log data recorded in a persistent storage medium; deciding master nodes of the one or more respective recovery candidate blocks; and re-reading the log data in order to permit proxy nodes of the one or more recovery target blocks to recover at least one recovery target block among the one or more recovery candidate blocks in parallel, at least one recovery target block among the one or more recovery candidate blocks being decided by the master nodes of the one or more recovery candidate blocks.
