  • Distributed systems and methods for database management and management systems thereof
    Patent number: 10152505
    Abstract: Methods for database management in a distributed system are provided, wherein the distributed system at least includes a plurality of servers. The method includes the steps of: collecting transactions to be executed, wherein each transaction corresponds to a plurality of requests and each request is associated with at least one data; generating a transaction dependency graph corresponding to the requests according to data dependency among the data associated with the requests of all the transactions; partitioning the transaction dependency graph to generate a plurality of partitions corresponding to the servers; generating execution plans corresponding to the partitions; distributing the transactions to the servers for execution based on the generated execution plans.

  • DETERMINISTIC DATABASE SYSTEM AND DATA TRANSFERRING METHOD THEREOF
    Publication number: 20160212206
    Abstract: A deterministic database system and a data transferring method thereof are provided. The method includes monitoring a workload of a resource server or a candidate server. When the workload meets a transferring requirement, the resource server starts to copy data to the candidate server. During copying the data, the resource server and the candidate server execute transactions together according to an execution order of the transactions, and then reply an execution result.
