Abstract
An exemplary embodiment of the present disclosure discloses a management method of a main memory database which is performed in a computing apparatus including one or more processors and a main memory which stores commands executable in the processors. The management method of the main memory database includes: generating a first log including information of change, which includes at least one of a data insert, an update, and a deletion of data recorded in the main memory, in the main memory; recording the first log in a permanent storing device to generate a first log file; and performing log compaction on the first log to generate a second log including only effective change information among change information on data in order to reduce a size of the log.
