Event Sourcing Framework that you can benefit during your transition towards CQRS

Enterprise-Scale Eventually Consistent Framework

Fork me on GitHub

Open Source

Initially open source, forever open source

Production-ready Stack

Benefiting from Kafka, Hazelcast and Cassandra 

Eventual Consistency

No blocking transactions by splitting read and writes, eventually consisting to the expected state 

eventapis is a Java based Event Sourcing framework which can be benefited by the teams who are planning to make CQRS transitions with minimum learning curve and ease of adaptation.

It has a unique architecture called Operation Store™ together with the stack elements including Docker, Kafka, Hazelcast and Cassandra.

High performance and highly scalable

New era of software is in transition from classical blocking architecture to loosely coupled and distributed architecture.

CAP Theorem

Consistency, Availability and Partition Tolerance cannot be archieved together


Command Query Responsibility Segregation

Event Sourcing

Sequence of events in order to achieve to the desired state

More BASE, no ACID!

BASE(Basic-availability, Soft-state, Eventually consistency) rather than ACID(Atomic, Consistent, Isolated, Durable) 

"I used eventapis framework in one of my project which helped me to get familiar with CQRS with a minimum learning-curve"
