func Lock

func Lock(key string, ttl time.Duration, flag string) (bool, error)

Lock attempts to acquire a lock with the given key and a time to live. flag is a unique identifier for the locking process.

It returns true if the lock is acquired, false otherwise.

func UnLock

func UnLock(key string, flag string) (bool, error)

UnLock releases a shared lock

If flag is not empty, it first checks if it's the lock owner before releasing it, preventing the lock from being released by an unauthorized process.
