Tartarus II is an in-progress reimplementation and extension of the original Tartarus system. It aims to surpass its predecessor in regards to stability, performance, and features. Started in the summer of 2022, Tartarus II is still in the early stages of development, but hopefully will soon become the preferred way of running a Tartarus server.
Tartarus II’s backend (Charon) is written in Elixir (originally Erlang). The choice to use a BEAM language was motivated by my observation of the inherent concurrency of the platform (many objects/players/scripts all interacting at the same time) and the ease with which this runtime facilitates such a model. The need to handle many simultaneous Websocket connections is also supported by the excellent Cowboy HTTP server.
Instead of the janky JSON serialized worlds the original Tartarus utilized, the new platform stores application state in a Postgres database, increasing both performance, and accessibility of this data.
