Summary:Embodiments of this application disclose an erasure code-based encoding method and a related device. The method includes: An encoder side obtains a plurality of data blocks in batches, and encodes the plurality of data blocks. In an ith time of encoding, after obtaining an incremental data block, the encoder side performs encoding processing on the incremental data block by using erasure code to generate an incremental parity block, the incremental data block includes at least one data block, and i is an integer greater than 1. The encoder side performs an exclusive OR operation based on the incremental parity block and an original global parity block to generate a first incremental global parity block. The original global parity block is a first incremental global parity block generated by the encoder side in an (i-1)th time of encoding, and an original data block is a data block obtained by the encoder side before the (i-1)th time of encoding. The first incremental global parity block is used to reconstruct a damaged data block in the original data block and the incremental data block. Encoding flexibility is significantly increased, the encoding processing at the encoder side is averaged, and a computing hotspot problem caused by full encoding is avoided.
