An experimental Event Sourcing database

This is an incomplete Work in Progress


xeDB is an experimentation platform for creating a specialized database for Event Sourcing applications.

In its first iteration, it aims to become a very minimal implementation of an Event Sourcing database, focused on write operations and consciously lacking sophisticated optimizations and caching, just to set a baseline.

The iterations following the initial experimental release are for incrementally improving and optimizing xeDB, measuring and comparing its performance with the previous versions.

The long-term goal is to develop a well-written, secure and fast database, specialized for Event Sourcing. One day, xeDB might even reach a level of stability, maturity and performance that it will be good enough for production use.


Currently, xeDB is not fit for practical use. Any non-experimental use, especially use in production, is strongly discouraged.

For development, xeDB uses Rust as its programming language and Cargo as its build tool and package manager.
