C # uses Redis to implement distributed locks

Redis has three of the most basic properties to ensure effective implementation of distributed locks:

• Security: Mutex, at any time, only one client can hold a lock.
• Active A: There is no deadlock, even if the client crashes while holding the lock, there will be other clients to obtain the lock, timeout mechanism.
• Active B: Failure tolerance, only the majority of Redis nodes survive, the client can still get locks and release locks.

The use of Stackexchange.redis is easy to implement.

Static voidLock () {Console.WriteLine ("Start ... .."); vardb =_redis.            Getdatabase (); Redisvalue token=Environment.MachineName; //actual item seconds kill here can be replaced by Product ID            if(Db. Locktake ("Test", token, Timespan.fromseconds (Ten)))            {                Try{Console.WriteLine ("working ....."); Thread.Sleep ( the); }                finally{db. Lockrelease ("Test", token); }} Console.WriteLine ("Over ... .."); }
