Request.objects.all().delete() is dangerous

If you call all() on a table with many rows, it will retrieve all the data at once, which will likely result in out-of-memory (OOM) errors.

As a workaround, make sure to set the SILKY_MAX_RECORDED_REQUESTS_CHECK_PERCENT very low (0.01 for example so it runs every 10_000 requests) and the SILKY_MAX_RECORDED_REQUESTS high (100_000 or more).

This way, the chances of running into this issue are much smaller (but still possible, depending on your load).

An even better workaround is to set SILKY_MAX_RECORDED_REQUESTS_CHECK_PERCENT to 0 and run the silky.Request.garbage_collect(force=True) method in a scheduled task through celery.

I previously used Celery to call this function to avoid deadlock, as suggested in the referenced comment. However, due to OOM errors, our scheduler failed to clear the database, leading to excessive database usage.

I recommend setting a limit and deleting the rows recursively instead. I will submit a pull request to address this issue.

I don't think that's true. It will retrieve data from the data if it is evaluated (e.g. through print() or otherwise). In this case, .all().delete() will issue a DELETE FORM <TABLE> without actually retrieving data so there should be no OOM in your python application.

Your pull request seems to tackle a different problem - since django-silk may be continually profiling and writing new rows into the database, it may conflict with DELETE operation unless the rows to be deleted are separate from newly written rows, hence the deadlock issues discussed in #265 and #294.

@albertyw I've thought like so, but no, django loads all to db because it needs to cascade delete related models.

The fix might also fix the deadlock problem.

The below is the raw SQL when I called Request.objects.all().delete().

It is possible to use
Request.objects.all()._raw_delete(Request.objects.db)
to execute DELETE query without loading all rows to memory.
If some db constrains are violated db would return error.
