- Use `SETNX` (Set if Not Exists) to set a key with a unique identifier (e.g., a UUID or a timestamp). - Optionally, set an expiration time to avoid deadlocks. 2. **Release the Lock**: - Use `DEL` to remove the key when the operat…

By using Redis for distributed locking, you can effectively prevent concurrent modifications and reduce the occurrence of `VersionConflictError`. The choice between a simple key-based lock and the Redlock algorithm depends on the complexity…
