Problems solved by technology

Since the storage mechanism provided by the existing kvdb is stand-alone storage, and the ledger data of the blockchain is constantly increasing, the total storage space of the stand-alone is fixed. Therefore, as time goes by, compared with the increasing ledger data, the area When the block chain node accesses data, the stand-alone storage mechanism will face the problem of insufficient storage space

Abstract

The invention relates to the field of distributed storage, and provides a bock chain node data access method, equipment and a computer readable storage medium, and aims to ensure that the block chain node has enough storage space when accessing the data. The method comprises the steps that when calling of a block chain node to a first access interface is received, whether each piece of historical target data is written into a target storage node or not is detected, and the first access interface is provided for the block chain node by a database cluster agent; the target storage node is a target server in a server cluster corresponding to the database cluster agent; if each data of the historical target data is not written into the target storage node, the historical target data is written into the target storage node; and data corresponding to the parameter in the target storage node is accessed according to the parameter transmitted when the block chain node calls the first access interface. According to the technical scheme, fragmented storage of the data is achieved, and equivalently, the storage space of the node is expanded.

Description

technical field [0001] The present invention relates to the distributed field, in particular to a method, device and computer-readable storage medium for blockchain nodes to access data. Background technique [0002] In the existing data access methods of blockchain nodes, when the nodes read and write the key-value database (kvdb), they are all implemented by directly calling the read-write interface provided by the bottom layer of the key-value database. Since the storage mechanism provided by the existing kvdb is stand-alone storage, and the ledger data of the blockchain continues to increase, the total storage space of the stand-alone is fixed. Therefore, as time goes by, compared with the increasing ledger data, the area When the block chain node accesses data, the stand-alone storage mechanism will face the problem of insufficient storage space. Contents of the invention [0003] The present application provides a method, device, and computer-readable storage medium...
