same time for thread safety, consistency, and good responsiveness.2. Decomposing the data modelSuppose that a data model must be shared by multiple threads and cannot implement a thread-safe model for reasons such as congestion, consistency, or complexity. Be able to consider the use of decomposition model design.V. Other forms of single-threaded subsystems in some cases, synchronization or deadlock problems cannot be avoided.
