How can I use aggregations to query distinct values across all time grouped by first seen

if numDocsProcessed % 10000 == 0:
elapsedSecs = int(time.time() - start)
dps = numDocsProcessed/elapsedSecs

@Mark_Harwood Just come across a bug in this script. If data is processed in less than 1 second the script throws a division by zero error. It is an edge case but simple to defend against.

if numDocsProcessed % 10000 == 0:
		elapsedSecs = int(time.time() - start)
                if elapsedSecs == 0:
                           elapsedSecs = 1
		dps =  numDocsProcessed/elapsedSecs
