Novel on-chain data high-speed retrieval model

Abstract

The invention provides a novel on-chain data high-speed retrieval model based on a built-in index and external connection data warehouse method. The model is composed of a block chain network in an improved index storage form, a data processing cluster and an application layer service. According to the novel block chain network, the organization form of transaction data of a traditional block chain system is improved, and a data structure suitable for high-speed retrieval is designed to organize the transaction data; the data processing cluster is responsible for synchronizing on-chain data to the under-chain relational data warehouse according to an efficient synchronization strategy under the condition of ensuring data consistency; and the application layer service encapsulates rich query functions supported by the relational database, and finally provides services to the outside in forms of HTTP, RPC and the like. By means of the model, the block chain system can be effectively expanded in the aspects of query efficiency, query functions and the like, and the query rate of data on the block chain is increased.

Description

technical field [0001] The present invention relates to blockchain technology and the field of improving retrieval efficiency in the process of data retrieval on the chain, and can be summed up as a new type of high-speed data retrieval model on the blockchain. Background technique [0002] In today's Internet era, with the emergence of massive data, the data query function and query speed on the blockchain chain have gradually exposed certain problems. When most blockchain projects are designed, they mainly focus on how to solve the problem of quickly reaching a distributed consensus in the process of data on-chain, while ignoring the on-chain data retrieval problem brought about by the emergence of a large amount of data. Limited by the underlying data storage mode and distributed storage characteristics of the blockchain, there are still problems that need to be solved urgently in terms of data retrieval on the blockchain, such as single retrieval function and low retriev...

AI Technical Summary

Problems solved by technology

These two solutions have certain disadvantages. Although the first solution improves the data retrieval rate to a certain extent, it is still not enough to meet the needs of real-time retrieval in most scenarios. At the same time, the query function is still only key-value type data. Does not support rich functions such as range query and fuzzy query

The second solution transfers the task of data retrieval to an external data warehouse, which meets the needs of real-time retrieval to a certain extent, but its data organization form has not changed, and the data retrieval of the blockchain system itself has not been improved.
