Embodiment Construction

[0025] This paper describes a log-structured storage system for storing data in, for example, a distributed ledger system (e.g., a blockchain network) and / or a blockchain-based centralized ledger system (e.g., a general auditable ledger service system) technology, the distributed ledger system and / or the blockchain-based centralized ledger system adopts the data structure of the blockchain to utilize the immutability, reliability and credibility of the data stored on the blockchain. In some embodiments, the distributed ledger system and the blockchain-based centralized ledger system may be collectively referred to as a blockchain-based ledger system.

[0026] In some embodiments, a blockchain-based centralized ledger system may be a centralized ledger system that provides time-critical auditing (with non-repudiation and tamper-proof), cryptographically verifiable and State-independent data ledger storage. In some embodiments, the blockchain-based centralized ledger system can...

Abstract

Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage devices, for data processing and storage. One of the methods includes maintaining, by a storage system, a data log file in a source storage device of the storage system. The storage system identifies one or more characteristics of the data log file and one or more characteristics of the source storage device, and determines a migration metric of the data log file based on the one or more characteristics of the data log file and the one or more characteristics of the source storage device. The storage system determines whether to migrate the data log file according to the migration metric. In response to determining to migrate the data log file, the storage system migrates the datalog file from a source location in the source storage device to a destination storage device.

Description

technical field [0001] This article deals with log-structured storage systems. Background technique [0002] A distributed ledger system (DLS), also known as a consensus network and / or a blockchain network, enables participating entities to store data securely and immutably. Without referencing any specific use case, DLS is often referred to as a blockchain network. Examples of types of blockchain networks may include public blockchain networks, private blockchain networks, and consortium blockchain networks. A consortium blockchain network is provided for a selected group of entities that control the consensus process and that includes an access control layer. [0003] Typically, each node of a DLS (e.g., a blockchain network node) stores or has a full backup of the blockchain network data, so that each node can be independent, and the local data at each node can be trusted to provide Serve. However, this storage scheme imposes demanding storage requirements and increas...
