DMA - data delay
« on: March 24, 2011, 01:23:22 PM »

Within a 15 minute report there is a delay in the data transfer.

Example

begin time 00:00
update time 00:15
receive time 00:30
transfer time 00:35

Is there a way of speeding this up?

Does the receive time have to be 15 minute after the initial data is created? If not, where is this set so that I can decrease the receive time?

Thanks

And why you need that so fast? Consider that there are several reports and all are FIFO, no parallel transfers that is why there are some delays with some reports.

@cav - I think I have and idea why "so fast"....

@janegriff: Your example is a slightly flawed, since it only shows 1 chunk of data passing through the ETL.  This is what is actually happening:

00:00 begin time (chunk 1)
00:15 update time (chunk 1), begin time (chunk 2)
00:30 receive time (chunk 1), update time (chunk 2), begin time (chunk 3)
00:35 transfer time (chunk 1)
00:45 receive time (chunk 2), update time (chunk 3), begin time (chunk 4)
00:50 transfer time (chunk 2)
...etc...

....you get the idea.. it's pretty busy around the 15 min aggregate.... and that's without the hourly, daily, weekly, etc...

I think my point is that this is *historical reporting* and your apparent urgency to display the results implies that you are attempting to use the Solution for *near-real-time* reporting.  I really would recommend that, if you need real-time results, you use CCPulse and perhaps plug it in to your Historical reporting, to fill the gaps.  i don't believe you will get the results any faster, unless you reduce the number of Objects of Statistics being gathered....
