Cheers, thanks!

Great, but those tables are tiny, only a couple of fields. The fundamental issue with POWERBI is its removing data from a SQL sever/DWH environment to store the data on its own environment and then process that data for visualization. While the SQL server (Synapse) sits with 60 clusters and numerous computing nodes, once it passed the data over to POWERBI, it takes a nap. Why ? The architecture just duplicated data storage, data is processed twice. Why ? My Spark pool is on constant holiday. Synapse cluster is taking a vacation. Where I need processing power is in visualization, processing, turning data into reports.

Very cool, this is extremely helpful. Well explained. Thank you

@@DataMozartHi again friend, how can i do to visualize both tables in one, depending on the date? That is, if(dateselected>15/10/2021(recent data), it shows data from hot_table,(else) it shows data from cold_table) That in 1 visualization. It's possible? Thanks a lot.

Great tutorial ! I have a question, I notice that you have a date table in your model. Do you make it correspond to the date of your two other table ?

It's a regular date dimension, so once you establish the relationship between the date table and fact table, date table will filter fact table

excellent info, thanks for sharing

This doesn't seem to work for more in depth visuals with a lot of unions in it . But it did work for simpler tables where all data is within the same table as long as i also turned of Totals column also.

Same question here...I hope you get an answer

what to do when I want to have high granular level details in my aggregated table...I want to create aggregated table with maximum possible drill down so that I can get all answers from agg table not go to fact table with DQ......But if i add multiple fields my agg becomes heavy...how do we tackle that..please advice

You can try creating multiple aggregated tables (with different columns/levels) by referencing to the same fact table

Can you have more than two hot/cold fact tables? Like a hot, cold, and coldest fact table? Working with ~300 million rows currently.

Hi Mariam, Absolutely! You can create as many tables as you want, but be careful because of the measure complexity.

While connecting sharepoint excel to power bi getting error as the data in the preview has been truncated due to size limits. Pls assist i need to link the file to bi

Great Stuff, thanks for the video! I have a question regarding this. Is it possible to make something like this with no aggreagation? I have a use-case where i want to have the last 2 months as "Hot" and the older data as "Cold", but because we show the data in a scatter plot with every measurement and limits up to the second, we cant aggreagate this. I tried appending the two queries (Import and Direct) but afterwards i saw its still import. Anyway, keep up the good work!

Hm, that's a good question Ray. Honestly, I'm not sure if that could work without aggregations. I believe you can get < 1 sec response from the hot data, but for the cold data it's hard without aggregations

Hello Ray did you find a way to do this?

Hi please suggest can i import 3-5 million records into power bi desktop from sql server... Is this possible for pro users. Thanks in advance

Hi, it depends how many columns you have, their cardinality, etc. But, in most cases, yes, 3-5 million rows can be easily imported in Power BI.

Shouldn't there be a connection between the Hot and Hot Agg table? So that Power BI knows how to traverse from one to the other?

Great question! Luckily, Power BI "knows" that on its own, so we don't need to set any explicit connection between these two. Hope this helps!

How to handle like 2,000 column😅😅😅😂😂😂??
