Why is Job only updating half of the data?

Question

Laravel

There is a Job that should update the records in the database. The problem is that for each run it only updates half. And so with each launch, always only ~ 50%. Starts at 7500, 3800, 1900, etc.
There are no errors in the logs. Why is this happening?

                        $address->street,
                        $address->lang

Answer 1

because you are updating the condition on which you make the selection.
Well, look, you have 1000 entries, for example, ID from 1 to 1000.
You take the first 50 and update. there are 950 not updated
A chunk makes limit +50
And the next selection you start with an indent of 50 records, as a result, records with ID 51-100 are skipped, and 101-150 will be updated.
the limit is again +50
, another 50 are skipped and so on.

Answer 2

Perhaps the runtime is interfering with this. It's best to remake this job so that it creates a lot of smaller jobs instead of processing all the records now. Besides such job to hammer a slot in queue for a long time.
Put horizon and you will see what happens to them.
