Abstract

The invention provides a method and a device for optimizing data reading and writing performance, and a medium. The method comprises: obtaining a write request of 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 comprising a first-level storage device, a second-level storage device and a third-level storage device; the first-level storage device being an external storage; the second-level storage device being a non-volatile memory; the three-level storagedevice being a memory; integrating data stored in the first-level storage device and the second-level storage device in the three-level storage system. Compared with writing-in into an external memoryand the memory in the prior art, the method and the device can improve speed of data reading and writing, and also can ensure persistence of the data, thereby optimizing data reading and writing performance, and reducing the amount of fragments in the first-level storage device, so as to improve the data reading and writing 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. ...
