Yes you can do scaled down testing in non-prod.  An example test may try 100,000 or 1,000,000 operations when in production you might see 100,000,000.  So you won&#x27;t catch subtle performance problems but you&#x27;ll catch order of magnitude problems (i.e something that is O(n) vs O(log(n))<p>Although in this case the test for this change may just EXPLAIN a known query and ensure the output matches what is expected.
