Answer
MySQL uses row-level locks, MVCC, adaptive hash indexing, and buffer pool optimizations. Proper schema design and indexing reduce contention.
Quick Answer
High-concurrency MySQL: use InnoDB (row-level locking, MVCC). Keep transactions short to minimize lock hold time. Use connection pooling (ProxySQL, application-level pools) to limit connection overhead. Read-write splitting: route SELECTs to replicas. Add read replicas for read scaling. Use Redis for caching frequently read data. Avoid long-running queries that hold locks and block others.
