How to configure it to auto-clear older then n records?

[TheKalpit]

How do I configure django-silk to delete (DB records & .prof files) older than x, say keep only last 1000 records?

I added the following in settings:

SILKY_MAX_RECORDED_REQUESTS = 1000
SILKY_MAX_RECORDED_REQUESTS_CHECK_PERCENT = 50

Doesn't seem to work. In fact, the server terminates without any error once the limit is reached.
I'm aware of the management command to clear the records, but that's a manual task (or additional effort to automate it). Is there a built-in way to do this?
