Conflict Detection and Resolution in an Event-Sourced System (Talk, EventSourcing 2020)
by James Geall

There are well established patterns for dealing with conflicting updates in traditional data stores (Relational, Key value) but how do you deal with conflicts when you have event streams? This talk will cover the existing patterns for conflict detection in traditional storage; how those patterns can be applied to an event sourced system; what requirements that places on your event store and how an event-sourced system can enhance the user experience when conflicts occur.
