Hello guys. One more technical question. As I see you disabled event behavior during default import processes and trigger all events manually. What was the purpose of it? I need also to trigger event in my custom import. Should i trigger it manually? Or can enable event behavior only during my import?

    bonjour! the background to disabling it is that in many cases there are a lot of duplicated events that would be fired during import. potentially hundreds of thousands.

    so we disable and accumulate the events and only fire them once, after import

    i think it could also be possible to activate the behaviour, but @UK9N7MP96 probably has more insight here

    There is also the issue with triggering events related to records that are inside a transaction that is not commited yet… Yhis can lead to issues…

    yes I found this hook during debugging) because I added event behavior to the database table but it didn't work. And found this hook then

    @U010MDPMB3N can you elaborate?

    If we don’t control the flow of the events, they will be sent to RabbitMQ with ids that are not yet saved on the DB. Then, when the workers process them, they will complain because the data was, at that point, not yet commited (pending transaction)

    ah, ok. another reason to accumulate first
