Abstract

The invention provides a data read and write performance optimization method, medium and equipment. The method includes: obtaining a write request for new data; according to the write request, using an IO scheduler to write data in a corresponding storage device based on a preset three-level storage system; the three-level storage system, Including: a primary storage device, a secondary storage device and a tertiary storage device; the primary storage device is an external memory; the secondary storage device is a non-volatile memory; the tertiary storage device is a memory; The data stored in the primary storage device and the secondary storage device in the above-mentioned tertiary storage system are integrated. Compared with writing to external storage and internal memory in the prior art, it can not only increase the speed of data reading and writing, but also ensure the persistence of data, thereby optimizing the performance of data reading and writing; and can reduce the amount of fragmentation in primary storage devices , thereby improving data read and write performance.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data read and write performance optimization method, medium and equipment. Background technique [0002] In the prior art, data write operations usually follow a write-through strategy and are directly written to permanent storage to ensure data persistence. In typical application scenarios, such as online shopping, the checkout information submitted by users needs to be quickly saved to the transaction database. The write operations caused by such transactions may be less than 1KB, while the typical database page size is 8KB. As another example, the update and modification of metadata by the database only involves writing a small amount of data, which needs to be stored on a persistent device immediately. The processing of data write requests spans multiple levels, including from bottom to top: block device manager, IO scheduler, file system and database management system. ...
