| description | The invention provides an adaptive local reconstruction code design method for hot data storage and a cloud storage system. Code word composition of the self-adaptive local reconstruction code comprises a data block, a local check block and a global check block, coding parameters can be adjusted in a self-adaptive mode according to the read arrival rates of the data blocks with different heat degrees, and a cloud storage system uses the self-adaptive local reconstruction code design method to store hot spot data. The method has the advantages that compared with an existing codeword, under thesame storage load or reconstruction cost, the larger local maximum throughput can be achieved according to different codeword parameters, the performance is improved by 50% or above, and the lower implementation cost is achieved; the self-adaptive local reconstruction code is more suitable for being applied to a cloud storage system.
