  • Greetings, @[email protected], that sounds like a truly wonderful idea, and as a fellow cat owner, it brings me great joy to hear about it. 😻

    In fact, I have recently changed the analysis of data, which is now performed in near real-time as soon as new data becomes available. I am currently working on the functionality to display multiple users (or, in your case, Pandora) on the map, which should be beneficial to your idea.

    Now, the primary question is, how can we integrate the data from the tracker into Reitti. Thats something I have no idea at the moment. Do you have any Infos about that?


  • This process is not triggered by any external events.

    Every ten minutes, an internal background job activates. Its function is to scan the database for any RawLocationPoints that haven’t been processed yet. These unprocessed points are then batched into groups of 100, and each batch is sent as a message to be consumed by the stay-detection-queue. This process naturally adds to the workload of that queue.

    However, if no new location data is being ingested, once all RawLocationPoints have been processed and their respective flags set, the stay-detection-queue should eventually clear, and the system should return to a idle state. I’m still puzzled as to why this initial queue (stay-detection-queue) is exhibiting such slow performance for you, as it’s typically one of the faster steps.


  • That’s good, but I still question why it is so slow. If you receive these timeout exceptions more often, at some point the data will cease to be analyzed.

    I just re-tested it with multiple concurrent imports into a clean DB, and the stay-detection-queue completed in 10 minutes. It’s not normal for it to take that long for you. The component that should take the most time is actually the merge-visit-queue because this creates a lot of stress for the DB. This test was conducted on my laptop, equipped with an AMD Ryzen™ 7 PRO 8840U and 32GB of RAM.



  • Hmm, I had hoped you say something like a Raspberry PI :D

    But this should be enough to have it processed in a reasonable time. What I do not understand in the moment is, that the filesize should not affect it in any way. When importing it 100 Geopoints are bundled, send to RabbitMQ. From there we retrieve them, do some filtering and save them in the database. Then actually nothing happens anymore until the next processing run is triggered.

    But this than works with the PostGis DB and not with the file anymore. So the culprit should be there somewhere. I will try to insert some fake data into mine and see how long it takes if i double my location points.


  • Thanks for the information. I will try to recreate it locally. In my testing I used a 600MB file and this took maybe 2 hours to process on my server. It is one of these ryzen 7 5825U. Since Reitti tries to do these analysis on multiple cores we start it with 4 to 16 Threads when processing. But the stay detection breaks when doing it that way, so it is locking per user to handle that. If now one of them takes a long time the others will break eventually. They will get resheduled 3 times until rabbitmq gives up.

    On what type of system do you run it?

    I will add some switches so it is configurable how many threads are opened and add some log statements to print out the duration it took for a single step.





  • I do not think it is that complicated. The front-end sends a request to the back-end with the current selected day. This triggers a search in Immich returning all photos taken on that specific day. This is returned to the front-end and this than does the heavy lifting like filtering them to the current map bounds, displaying them on the map at a specific location. We proxy all request from the front-end through our server because of CORS issues and I did tried to avoid having to configure Immich besides creating a token for the API.

    One would need to either create a specific IntegrationService like ImmichIntegrationService and then figure out a way how the user can configure that. The easiest would be that we just then call all available ones even if I do not see the use case of having multiple Photo-Servers. But it would make the code in Reitti cleaner and would not hurt if we do not configure 20 simultaneous servers :D
