What are the downsides of event sourcing?

Event sourcing can lead to increased complexity in managing event stores and can make querying data more challenging.

Can you explain why querying is more challenging?

Sure! Since data is stored as a series of events, reconstructing the current state requires processing all events, which can be slow.

Are there any performance issues associated with event sourcing?

Yes, performance can degrade if the event store grows large, as replaying many events can become time-consuming.

What about data consistency? Is that a concern?

Absolutely! Ensuring data consistency can be tricky, especially in distributed systems where events may arrive out of order.

How can these downsides be mitigated?

Mitigation strategies include using snapshots to reduce replay time and implementing strong consistency models.
