Abstract

The embodiment of the invention relates to a data reading and writing method and device. The method comprises the following steps: determining a target data block cluster space to which a target datablock to be read and written belongs; determining a target storage address corresponding to the target data block according to the initial address of the target data block cluster space, the space size of a block node in the target data block cluster space and the block index of the target data block; and performing read operation or write operation on the target data block according to the targetstorage address. Therefore, rapid addressing can be realized, and the data storage and retrieval efficiency is improved. Furthermore, by applying the data read-write method provided by the embodimentof the invention in the blockchain scene, the storage and retrieval efficiency of the blockchain data can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data storage, and in particular, to a method and device for reading and writing data. Background technique [0002] At present, blockchain storage mostly adopts the method of memory block data, and stores blockchain data in KV database or files. Taking the KV database as an example, the KV database is a database that is organized, indexed, and stored in the form of a key-value (Key-Value). When storing blockchain data, a key-value pair is established for each block, where Key stores the hash value of the block, and Value stores the data of the block. When retrieving the blockchain data, traverse the key-value pairs according to the hash value of the blockchain data to be retrieved, and find the corresponding Value, that is, the blockchain data. It can be seen that in the current method, the efficiency of blockchain data retrieval is relatively low. Contents of the invention ...
