Data writing methods, storage devices, storage media and computer program products

Abstract

This application discloses a data flushing method, storage device, storage medium, and computer program product, relating to the field of computer technology. The method involves dividing a cache pool into at least one cache unit, the size of which is determined based on the stripe width and stripe block size of the disk array. Compressed data blocks obtained by compressing original data blocks are first written into the cache unit for aggregation. When the amount of compressed data blocks stored in the first cache unit meets the full stripe requirement, the compressed data blocks in the first cache unit are flushed to the disk array, ensuring that the data flushed to the disk array is full stripe. This eliminates the need for locking operations to wait for data accumulation, thus avoiding lock contention and preventing storage space waste caused by excessive redundant data. Therefore, it solves the technical problems of lock contention caused by multiple locking operations waiting for data accumulation and the waste of storage space due to redundant data, achieving the technical effect of avoiding lock contention and saving storage space.
