I have set up a basic example using aggregates, commands, events and a projection using axon-spring-boot-starter 4.1.1
It works, but I’m having difficulty to find proper documentation or tutorials to extend on it.
Every time I restart the server I see the events being replayed in my projection (backed by a persistent solr repository)
As a next step I would like to have more control in replaying events.
I would like a setup where by default the events, that were already processed, are not being replayed in that projection.
And I would like to do a REST request that rebuilds the solr repository from all events.
I have tried to read the Axon documentation, different blogs/articles and github examples, but it’s difficult to
combine all the snippets of information.
The Axon documentation states that by default Tracking Event Processors are used, which I think are the type that can track
the event offset. The offset must be persisted somehow, so I assumed that the TokenStore is somehow important in this.
I therefore created a JdcbTokenStore bean (postgres datasource).
When I start the application after that I receive the following warnings:
Fetch Segments for Processor ‘myquery’ failed: Could not load segments for processor [myquery].
I have not yet created any scheme in my postgres database. Is this message related to this?
I could not find any information if this is done automatically, or what steps I need to do for this.
I would appreciate any answer on the above questions or tips how I can become proficient using Axon.
The technology seems really cool, but the learning curve seems rather steep.
