Laravel-excel: [QUESTION] Allowed memory size. Bug or not?

Your PHP process runs out of memory when reading your view file. I think 500000 rows is a bit too much for the FromView strategy. You can try the approach this article took: https://stefanzweifel.io/posts/lazy-collections-in-laravel-excel/

I cant use cursor() because use Laravel version: 5.5.*. And I get the data not only from database, through calculations in php, because the database does not allow such calculations. In any case, I will have an array with 500,000 rows, before I give it to the generator Excel file.

@patrickbrouwers I tried the approach from the article but I get:

Return value of Maatwebsite\Excel\QueuedWriter::exportCollection() must be an instance of Illuminate\Support\Collection, instance of Illuminate\Support\LazyCollection returned

@fedeisas which version of laravel are you using?

@patrickbrouwers

laravel/framework                            v6.18.1            The Laravel Framework.
maatwebsite/excel                            3.1.19             Supercharged Excel exports and imports in Laravel
phpoffice/phpspreadsheet                     1.11.0             PHPSpreadsheet - Read, Create and Write Spreadsheet documents in PHP - Spreadsheet engine

I'm using queued writes. Maybe that's the issue?

I'm trying to do exports on distributed workers (using S3) and the FromQuery is painfully slow (1 hour for a 30k rows export).

So I'm trying to switch to lazy collections and cursor() with no luck.

@fedeisas use queue failed with error
Return value of Maatwebsite\Excel\QueuedWriter::exportCollection() must be an instance of Illuminate\Support\Collection, instance of Illuminate\Support\LazyCollection returned
but Excel::download is OK

i still can't export 60K data with FromQuery concern or LazyCollection with 512M memory setting

any other setting to implement this?
