DATA MANAGEMENT METHOD AND INFORMATION PROCESSING APPARATUS

摘要

A first node is assigned a first data group, and a second node is assigned a second data group. In addition, the second node manages a backup copy of the first data group. The second node receives, from the first node, a log indicating an instruction executed on a data record belonging to the first data group, and stores the received log in a memory of the second node. The second node writes logs for a plurality of instructions accumulated in the memory into a storage device of the second node different from the memory when a predetermined condition is satisfied.

主权项

1. A non-transitory computer-readable storage medium storing a computer program, the computer program causing a computer to perform a process, which computer is used as a second node in a system including a first node responsible for a first data group and the second node responsible for a second data group and managing a backup copy of the first data group, the process comprising:
receiving, from the first node, a log indicating an instruction executed on a data record belonging to the first data group, and storing the received log in a memory of the computer; and writing logs accumulated in the memory, each of which indicates one of the instruction in plurality, into a storage device of the computer different from the memory when a predetermined condition is satisfied.
