UnverifiedThe workspace generation mechanism is highly similar in principle to optimistic locking version numbers in databases: it does not prevent old data from being written to disk but ensures old data is identified and rejected at read time76% similarUnverified防止重复扣费的幂等性实现方案包括数据库唯一约束、状态机检查、Redis分布式锁和乐观锁版本号72% similarUnverified悲观锁（SELECT ... FOR UPDATE）在查询时锁定数据行，适合写多读少场景但性能较差70% similarUnverifiedTraditional relational databases (such as MySQL and PostgreSQL) can experience performance bottlenecks in high-concurrency write scenarios due to locking mechanisms, write amplification, and primary-replica replication latency.70% similarUnverifiedUsing SELECT FOR UPDATE SKIP LOCKED is the common approach for modern database-based task queues to implement exclusive claiming and failure recovery.69% similar
