AI Technical Summary

Technical Problem

In existing technologies, the Ceph distributed file system requires multiple SSD hardware disk write operations and database operations during data updates, resulting in low performance.

Method used

By updating data directly in the original location on the hard drive at the software level and using the garbage collection mechanism of the SSD hardware to manage old data, the database operations during disk write operations and metadata changes are reduced, and the data update process is optimized by combining SSD hardware and Ceph software.

Benefits of technology

This reduces the number of SSD hardware write operations, improves write request performance, and ensures data reliability by modifying the SSD garbage collection mechanism, thus achieving more efficient data updates.

Abstract

This application discloses a data update method, apparatus, device, and medium, relating to the field of computer technology. The method includes: acquiring a data update request and determining data information to be updated and data attribute information based on the data update request; determining local target historical data information and combining the data information to be updated and the data attribute information to obtain target data information to be updated; replacing the target historical data information with the target data information to be updated; and writing and saving the target data information to be updated and the target historical data information to a hard disk. Through the above technical solution of this application, disk write operations on SSD hardware can be effectively reduced, database operations during metadata changes can be reduced, and write request performance can be improved.
