Yes, it is the same - but, as an example, i have had messaging running about every 5 seconds.  So it can be rather quick response.  The whole loader process is actually quite elegant.  The quartz mechanism scales to many hosts - all those running the loader.  TIER packaging has moved to calling it the daemon - better terminology (I personally don’t like the word but loader isn’t good either).  Don’t get hung up on the loader and changeelog - just use it.  It’s cool stuff.

Now all that said, the only item in all this that worries me is the tempchangelog to changelog processing.  It’s a necessary evil cuz this is where changes are labelled/categorized.  It’s also the single threading aspect of processing changes that worries me the most.  Make sure these tables are on fast storage, properly indexed and so on - usual stuff.  Beyond that - like I said - good stuff.

I hope this helps.

Greetings team,

 

How does the RabbitMQ messages get processed. Is it similar to the psp where changes go into the changelog and a process then periodically polls it? Or do messages get sent as soon as they are sent to the changelog? My guess it’s still a polling system since changes can come in from the WS or UI but the loader has traditionally been the “batch” processing component which does the back end stuff.

 

Thanks
