Hello

2011/1/19 Ozz Nixon <ozznixon(at)gmail(dot)com>:
> A while back someone answered a question I was running into - poor performance on count(*) from a table which is constantly growing. The answer was like looking at oracle's V$ table - and I could get a semi-current count. (I do not need the exact count - just checking to make sure the table is growing).
