Key value data storage method, device and equipment, and storage medium

Abstract

The invention provides a key value data storage method, device and equipment, and a storage medium, and the method comprises the steps: obtaining the number of first physical blocks in a first physical block set in a three-dimensional flash memory; Judging whether the number of the first physical blocks reaches a first preset number or not; if the judgment result is no, obtaining the position information of the first physical block written in the previous time; obtaining the position information of the currently written first physical block according to the position information of the first physical block written in the previous time; wherein when the data blocks in which the key value data is not written exist inside and outside the three-dimensional flash memory at the same time, the regional information of the currently written first physical block is different from the regional information of the previously written first physical block; and storing the key value data to the currently written first physical block according to the position information of the currently written first physical block, so that the currently written first physical block is far away from the previouslywritten first physical block, and the situation that the temperature is sharply increased due to frequent operation on the physical blocks in the same region is avoided.

Description

Technical field [0001] The present invention relates to the technical field of data storage, in particular to a key-value data storage method, device, equipment and storage medium. Background technique [0002] The data in the key-value storage database is organized, indexed, and stored in the form of key-value pairs. Key-value data storage is very suitable for business data that does not involve too many data relationships and business relationships. At the same time, it can effectively reduce the number of reads and writes to disk, and has better read and write performance than other database storage. [0003] In the existing key-value data storage, chip storage with a planar structure is used, and keys and values ​​are stored separately. For data that needs to be frequently written and updated, each time the value of the log file is garbage collected, it is necessary to determine whether the currently stored data is valid in the data structure where the key is stored. If it is...
