Moving from Tracking to Subscribing event processor

Axon Framework
1

Hello,

We have tracking event processors for event handling and we want to switch to subscribing event processors for our use case. We used tracking event processors for a long time and we are looking for a smooth transition.

We think that we can close our app for a limited amount of time to make sure all the events are processed then we will switch to subscribing but we are concerned that there might some errors that can corrupt our data.

Is there any way to do smooth transition?

Hi Alperen,

Can you maybe explain why you want to move? A subscribing event processor will only ‘see’ the events within the same JVM, making it likely to miss events in certain conditions.

It’s hard to think of scenarios where a subscribing event processor can be preferred.
