TheOmenDen's EventStore

A simple, lightweight Event Sourcing solution

• Borrowing concepts heavily from Daniel Miller's article on CQRS and Event sourcing, we've packaged up some of that solution, and mixed with Asynchronous streams to bring hopefully the best of both worlds.
• We aim to provide a persistence method that is suggested but not enforced with this, thus allowing the end user to define their own way to persist events within their own methods.
• We aim to provide a way to interface with popular messaging queues/service busses in the .NET environment.

The case for our implementation

Performance

• Hopefully by using IAsyncEnumerable<T>, we can take advantage of the potentially long-running retrivals of reconstructing entities from events
• Providing overrides for common methods with async ... await patterns to help delegate concurrency issues
• Minimizing the use of Concurrent Collections to help reduce overhead - these may prove to be necessary for integrity

Extensibility

• Using generics, and being a bit more liberal on the use of pipeline-esque interfaces we aim to have a more "plug and play" messaging/subscribing system
• By working with this concept we aim to provide a modest way to integrate our "out of process" events with an "in-process" library like MediatR

Minimal external dependencies

• While we can't avoid certain dependencies, we do aim have as few as possible to prevent rough loading times
• We also aim to use only relevant dependencies for our end goals.

Continuing Development

• As a work in progress (WIP) this library will be updated, and improved on as time goes on, and our knowledge gets deeper.
• This is of course a work in progress, all code is "as-is", and does not provide any coverage, warranties, or guarantees.
• Use at your own risk, and under your own discretion
