DATA PROCESSING METHOD OF IN-MEMORY DATABASE USING SNAPSHOT, AND IN-MEMORY DATABASE

摘要

The present embodiments provide an in-memory database which reduces memory usage, minimizes variability in memory usage, and enhances database processing speed by generating a temporary log file in text file format on a block device, setting a storage location flushed from a log buffer in a memory so as to indicate the temporary log file when the temporary log file is generated, generating a temporary snapshot file in binary file format on the block device after setting the storage location so as to indicate the temporary log file, and periodically flushing log records in small units.
