Domain Modeling / Core

Name	Links	Status	Description
DomainModeling	code		Contracts for DDD/CQRS development
Cronus	code		Cronus is a lightweight framework for dispatching and receiving messages between microservices with DDD/CQRS in mind

Messaging

Name	Status	Description
RabbitMQ	olympus	It works so well that we do not need to implement other messaging.

Event store persistence

Store	Status	Description
Cassandra	olympus	This persister is in production since 2013 and it is recommended for production purposes.
MSSQL	styx	The persister has been used in production with Cronus v1 but MSSQL is relational database and it does not fit well as an event store persister.
GIT	tartarus	Persister exists just for fun.

Serialization

Serializer	Status	Description
Json	olympus	It is recommended to use the serializer with DataContracts
Protobuf (Proteus)	styx	This has been the prefered serialization with Cronus v2. However, there is a huge warm up performance hit with big projects which needs to be resolved. Despite this, it works really fast. The implementation has small protocol changes

Projections persistence

Store	Status	Description
Cassandra	olympus	Stores projections in Cassandra
ElasticSearch	olympus	Builds projections dynamically. Very usefull for projects which just started and changes occur frequently. However, it must be switched to another persister such as Cassandra after the initial stages of the project
AtomicAction	olympus	Aggregate distributed lock with Redis

Other

Name	Status	Description
Hystrix	olympus	Circuit breaker middleware for Cronus
Migrations	olympus	Middleware to handle migrations of any kind
