Best practice to report data when using chunk imports

[gabva]

Hi,

I'm currently using chunk imports it's working great
However, i need to merge data between chunks and send them to the AfterImport event.
Eg :
first chunk has : 1000 rows , found 100 users in db
second has 1000 rows , found 152 users in db

how to keep the first 100 users , add the 152 and send it to the AfterImport event ?

tried public $users and used $this->users, but in collection() method it's being reset for each chunk

Thanks a lot for any help or advice

I'm not sure I fully understand what you are trying to achieve, but perhaps storing the user ids in a redis store (or cache)?
It's indeed intended that $this->users is reset on each chunk to save memory.

Hi Patrick Thank you for replied my problem. I think you understood well. I need to build an unique report merging all the chunks. I have thought about cache, I was not sure it was a clean solution.
