CDR Records Purging by CCM 4.1

Unanswered Question
May 20th, 2009


In my CCM 4.1 the MAX CDR Records is set as 1500000. I want to know how CCM purges the record when the count reaches 1500000. Does it deletes all of them at once(or it deletes them based on some condition?) and the records again start increasing from 0 to 1500000.



I have this problem too.

it simply starts deleting oldest records, think of this as a circle, once you complete a whole turn you start writing were you started

But does it keep on deleting from the oldest till the count becomes zero?

and then waits for the record count to become 1.5million before it starts to purge again?

I thought the circle example would be enough, apparently not

If you have 10 slots and imagine them in a circle, the next element to 9 would be the 0


When you reach data 11 you replace 0, 12 replaces 1, 13 replaces 2, etc and so on til the end of times. You never really delete, but rather replace data.

It's a circle, you replace the elements.

When you write data 1,500,001 you delete the 1st entry you have in DB, which is the oldest and so on

Is it clear now?
