Reducing data size - remove columns or merge with 2nd table size
Hi Anonymous ,
Can you provide more details like below which might help to narrow down the bottleneck and resolve the issue -
Are you doing Incremental refresh and still you have this much data and performance is slow?
Any Network related issues during your refresh which might be causing the delay?
Best Regards,

I'm not using incremental refresh.
It's a recently created report. I created it in desktop with a weeks worth of data, now I've published it to service for 3 months worth of data and the file isn't loading (the circle spinning icon just goes for an hour+). I'm trying to use the manual refresh icon in Service "dataset + dataflows" tab.
Table A is a several .dat files on sharepoint appended in M query.
I've used this advice to create Table A, then use it as an internal source before merging with Table B in a seperate query

No network issues I'm aware of. It wasn't loading Friday when i first tried, and still isn't today.
The dataset is currently connected to 3 .dat files (in csv format). each .dat file is a month worth of data and around 5-5.5gb each.
