Flux and cqrs

About flux and cqrs, what do I want to write about this??? Things I want to find out. actions in the past: because it’s something that has happend. nothing todo about it. deleting actions is not possible, only update. Store all actions in an event store for replay? How about authentication and validation actions and flux. For example: action ‘MESSAGE_SUBMITTED’. But the message must be validated before it is added. The MessageStore is responsible for validating because it’s specific logic of the store. »
