Aggregate changed: How to handle snapshot store #910
Description
EventFlow has the concept of event upgraders when a new version of an event looks different. Is there also a concept with regards to the snapshot store?
If a new version of an event needs to be implemented the aggregate may also change. I am using the EF Core snapshot store implementation. Do I have to delete the snapshot store in this case? How can I repopulate the snapshot store?
Is there an existing concept / solution for this kind of issue?
Regards,
Christian
