UnverifiedIn WAL mode, read and write operations can proceed simultaneously; read transactions read the main database file plus committed portions in the WAL, while write transactions only need to append to the WAL, providing MVCC-like snapshot isolation concurrency control.75% similarUnverifiedThe uv sync command reads the uv.lock file to ensure that the versions of dependencies installed are exactly consistent across different operating systems.63% similarUnverifiednvcc 编译器提供了数十个优化开关，涵盖寄存器分配、指令调度、循环展开、内存访问模式等方面62% similarUnverified乐观并发控制（OCC）是一种无锁并发策略，通常通过版本号实现：读取时记录版本，写入时附带该版本号，若当前版本不符则写入失败并重试59% similar
