Q & A

What is SpaceTime DB, and how does it relate to multiplayer games?

SpaceTime DB is an all-in-one backend solution designed to simplify the development of multiplayer games. It combines essential backend features—storage, compute, and networking—into a single system, allowing developers to create scalable, real-time multiplayer games without requiring extensive infrastructure or a large team.

How does SpaceTime DB simplify the traditional MMO development process?

Traditional MMO development requires complex distributed systems and infrastructure, involving multiple services like databases, networking, and game servers. SpaceTime DB simplifies this by offering an easy-to-use platform where developers can manage storage, compute, and networking in one place, significantly reducing the complexity of backend development.

What are the three foundational ingredients that SpaceTime DB focuses on?

SpaceTime DB focuses on three core ingredients: storage, compute, and networking. These components are essential for creating multiplayer games and are handled efficiently within the system, making it easier for developers to build scalable applications.

Why is SpaceTime DB faster than traditional databases for game development?

SpaceTime DB stores data in memory close to the code, reducing overhead compared to traditional databases, which involve multiple network hops and query processing. This architecture allows for ultra-fast query execution and real-time data updates, resulting in better performance for multiplayer games.

What is the role of 'reducers' in SpaceTime DB?

'Reducers' in SpaceTime DB are stateful, transactional cloud functions that perform computations and update the database tables. They are equivalent to game server code, where developers can define custom logic, such as physics calculations or player interactions, in a simple and efficient manner.

How does SpaceTime DB ensure security for multiplayer games?

SpaceTime DB ensures security by running modules in secure, sandboxed WebAssembly instances and implementing fine-grained access control. Clients can only interact with the data through reducers, and data access is restricted based on authorization logic that developers define, preventing malicious access.

How does SpaceTime DB handle real-time updates and interactions?

SpaceTime DB supports real-time networking by using 'subscription queries,' which allow the database to evaluate and return query results while maintaining a persistent connection. This ensures that clients receive real-time updates as the game state changes, providing smooth interactions in multiplayer environments.

What types of applications, besides games, can benefit from SpaceTime DB?

SpaceTime DB is not limited to games. It is also ideal for building real-time multiplayer applications like collaborative editors, such as Pogle, a tool for streamers to manage their streams with moderators. The system's simplicity and scalability make it suitable for various types of multiplayer apps.

How did the development of 'Delivery Z' benefit from SpaceTime DB?

'Delivery Z,' an MMO developed by a small team of eight people, benefited from SpaceTime DB by using its backend to create a persistent, multiplayer open world with minimal backend work. The development team focused 95% of their time on the frontend, with SpaceTime DB handling the backend effortlessly, enabling rapid iteration.

What is SpaceTime DB Main Cloud, and how does it differ from the standalone version?

SpaceTime DB Main Cloud is a managed, multi-tenant cloud service that makes deploying applications into production even easier. Unlike the standalone version, which is a single-node deployment, Main Cloud allows developers to publish their applications seamlessly in the cloud without worrying about the underlying infrastructure.
