We held out on Cassandra for as long as we could - it’s a very fast and scalable database, and it’s been tried and proven at a scale unlike any other ( Apple’s cluster surpassed 75k active nodes). However, as we grew and discovered more and more query needs, Cassandra’s denormalization patterns and lack of flexible indexing began to be a real and very noticeable constraint, especially since its severely limited range queries meant that implementing our own higher-level indices on top of its out-of-the-box functionality would be a very difficult endeavor. Initially, this went well, as our data model has always been designed to be as simple and straightforward as possible in terms of database representation. Prior to porting our database backend to use CockroachDB, we were using Cassandra. Cassandra Is Scalable But Limits Design Choices We use the Jetty HTTP server for our embedded HTTP needs, and the client-side UI is done with JavaFX. The world simulation is handled through an in-house entity system, and scripting is done in a powerful high-level in-house scripting language (object oriented with classes, first-class functions, dynamic typing, and polymorphism). At a higher level, our physics engine is Bullet and we use the jMonkeyEngine game engine both server side and client side. The database layer is based on a lightweight ORM pattern - the Postgres JDBC driver, a HikariCP Connection pool, and the jNimble ORM with a thin layer on top of it to map our domain objects to/from SQL (all queries are handwritten for design flexibility and performance - we don’t use the automatic mapping features of jNimble right now). Under the hood, our tech stack builds heavily on a combination of in-house code and some of the best open-source software in the industry. Lastly, we need any database we use to be open-source or open-core - this openness is central to MyWorld’s heritage and design philosophy, and since MyWorld will be open-sourced at some point after the alpha and beta releases we could not consider closed-source or vendor-locked databases. In addition, we want a database that follows our own philosophy of making software that self-maintains as much as possible and requires minimal human interaction to operate. Easily handle a multi-terabyte dataset.Handle the database traffic needed to support millions of concurrent players,.Replicate data to minimize the odds of downtime and data loss,.Scale linearly along with the simulation cluster,.To accomplish this, we need a database that can: At MyWorld, we’re building a brand new virtual world platform from the ground up, using modern tools and technologies to create a fast, scalable, and extensible platform to power the next generation of social virtual worlds and massive multi-player online games. MMOG (Massive Multiplayer Online Game) developers lack a common, extensible platform, meaning that multiple years of work and millions of dollars are required to build a custom engine for almost every MMOG - forcing indie studios and many other small developers out of the market entirely. Current social virtual worlds (like Second Life and OpenSimulator) are built on decades-old technology and are fundamentally limited in their design. MyWorld is a next-generation virtual world startup. We’re refreshing it today in light of recent conversations that have come up around the capabilties of Cassandra as they compare to CockroachDB. * Editor’s note: this blog was originally published in 2020. ![]() Also, if you’d like to guest author a blog about your project please reach out on our community slack channel.
