Event Sourcing in Python¶
A library for event sourcing in Python.
What is event sourcing? One definition suggests the state of an event sourced application is determined by a sequence of events. Another definition has event sourcing as a persistence mechanism for domain driven design. In any case, it is common for the state of a software application to be distributed or partitioned across a set of entities or aggregates in a domain model.
Therefore, this library provides mechanisms useful in event sourced applications: a style for coding entity behaviours that emit events; and a way for the events of an entity to be stored and replayed to obtain the entities on demand.
This documentation provides: instructions for installing the package, highlights the main features of the library, describes the design of the software, the infrastructure layer, the domain model layer, the application layer, and has examples and some background information about the project.
