Redis
-
Redis is an in-memory storage system, often used as a cache or fast database to improve application performance, including multiplayer games. It is not a low-latency networking engine by itself, but can be used to coordinate game state data, server synchronization, and maintain real-time state variables.
-
Redis is an in-memory database that primarily uses the TCP protocol for communication. It is designed for fast access and data caching, but is not a network transport solution for UDP. In network scenarios, Redis is usually combined with other technologies that handle UDP transport, but Redis itself is not a UDP transporter.
-
Advantages :
-
Very fast and ideal for temporary storage and quick access to data that needs to be shared in real time.
-
Redis offers replication, persistence, and clustering features, aiding scalability.
-
-
Disadvantages :
-
Does not provide a complete network solution, mostly used as support in networking and game server setups.
-
Working with Redis requires a network structure to consume the data (e.g., Photon , KCP , or others).
-
-
Pricing Model :
-
Redis is free and open-source under the BSD license for on-premise use.
-
Paid versions (like Redis Enterprise ) offer extra features, advanced scalability, and cloud support.
-
-
Ideal Scenarios :
-
Real-time games and applications needing fast cache and data sharing across multiple server instances.
