Abstract: Embodiments of the disclosure provide a blockchain consensus method, apparatus, device, and storage medium and relate to the field of blockchain technology. The method includes determining, from a plurality of sub-blockchains, a target sub-blockchain to which a target block belongs, and adding the target block to the target sub-blockchain, where the target block is generated based on transaction data or obtained by synchronizing with other nodes; obtaining, from the plurality of sub-blockchains, a sequence of valid blocks for each of the plurality of sub-blockchains, where each sequence of valid blocks includes at least one valid block; and globally ranking the obtained valid blocks based on a logical clock corresponding to each of the obtained valid blocks, to obtain a global blockchain.

Abstract: A data partitioning method for a distributed parallel database system, comprising creating fact tables and dimension tables according to a constructed distributed parallel database system, inserting records of the dimension tables and the fact tables into nodes according to partitioning rules, replicating the records of dimension tables into the nodes that include fact tables, performing data deletion, and performing data update.
