I have in the past used parallel hints to speed up a count(*) kind of full table scan query.

Hi Gurus,

In one of our insert intensive application we are inserting around 3-4 million rows / hour. Also this app needs to do a count(*) of the tables every 10 minutes for verifying some application based logic. This is really killing us and it takes a lot of time.

Can you please guide me to a direction ( built in functions or something similar).

Actually this app is being ported from Informix. Informix can somehow keep a trak of the count(*) of a table in its header somewhere.

And yes I have tries count(1) , count(indexed_column) etc.

Thanks In Advance.
