Cronus is a lightweight framework for building event driven systems with DDD/CQRS in mind

Cronus is a lightweight framework for building event driven systems with DDD/CQRS in mind.

Important

We have several success stories using the Cronus framework in production and we want to share this success with a wider audience. Hence, the main goal we are working on now is documenting the framework and providing samples. We hope this will attract contributors and allow more developers to build applications with it. You can keep an eye on the process on our project board or the milestone where we track the progress.

cronus's Issues

NuGet Package

Cronus cluster

Move deletion of old snapshots to a background process/thread

Write Sanity tests into Cronus

Rename the scopes to unit of work, cuz its a unit of work pattern, and make them implement the rollback capability

Do not allow more than one BC per Cronus Host

Federate/Cluster Rabbit MQ

IEventStore is absurd. Get rid of this SqlConnection poison.

Move the messages that are causing errors to error queues

Should make _nuget.bat pull all packages from nuget repo

Make the interface IAggregateRepositry generic i.e. IAggregateRepositry<AR>

Move the method definition AggregateRootState<ID>.Apply(IEvent @event) to interface and excplictly implement it

Conventions Documentation

Move "Multithreading" into a separte nuget package

Add synchronius in memory implementation

Introduce ICommandHandler and IEventHandler

We should explicitly specify that the app services are handling commands and the ports are handling events.Currently an app service can handle events...

Add script to publish new version to NuGet

Parent #49

On Dramatic Errors go to error queue

When replaying events,if there is an event without a handler the process can not finish

Log warning messages processing a message without a handler

Move "#if DEBUG ValidateSnapshotsBoundedContext(states);" to configuration

Currently Cronus Exits on Exception in any of the handlers :)

Configurations

Introduce some form of response after sending a command

Discuss adding SupportReplayAttribute and NotSupportingReplayAttribute

Write persistence tests for MsSql

Retry Commnads On Concurrency Exception

Convention Tests

a

Add nuget packages for Automated Santiy test

Abstract the serializer

Remove the extension method BlockDeque(IBatchScope scope)

Rewrite the build scripts to use F# Fake

Make the samples work with Puppet

Sample with read model using Cassandra

Sanity Tests

App services crashing when there are no events in the message commit

Add SandCastle documentation and link it with Azure Host

Move RabbitMqTransport into a separate nuget package

Performance Analizer

Remove the base class Command and Evet (Branch it before that so we have a working pord version)

Aggregate Reposotry( for tests)

Add AppHarber CI for builds

Unit Of Work Abstractions
