Latest Patents

Pei Zhang's latest patents include innovative methods for data replication in a distributed storage system. In this patent, data is replicated between primary and secondary storage systems using either a data pulling process or a log shipping process. When utilizing the log shipping process, a transaction and its associated data are stored in a transaction log within the secondary storage system. Upon execution of the transaction, the actual data is persisted from the transaction log to a data log in the secondary storage system. Alternatively, if the data is replicated through the data pulling process, the transaction is stored in the transaction log, while the associated data is retrieved from the primary storage system and stored directly in the data log of the secondary system.

Another significant patent by Pei Zhang focuses on data partitioning in a distributed storage system. This system comprises multiple partitions, and a block received for storage is striped across these partitions if it meets predetermined criteria. Multiple tables are maintained for indexing the blocks and subblocks of the partitioned data. The tables for the subblocks and their corresponding blocks are updated to include metadata, facilitating the retrieval of subblocks in response to requests for the stored blocks.
