Great tips.. I always use Remove other Columns to make sure I only keep the columns I need.. always get rid of the columns as a first step and not after you have done bunch of transformations.. plus always, always reduce the date-time to date only if you dont need the time. Time adds lot of bulk to the size (i guess because of high cardinality). hopefully PowerBI team will add Vertipaq analyzer-like tool in performance analyzer

Just used this as a step by step to analyze a model that I am working on. I knew I had to get rid of columns (and I had) but now I am pruning even more ruthlessly. And one thing I would add--don't be afraid to remove columns--you can always add what you need back. So what I do is select JUST the columns I know I want, and then use REMOVE OTHER COLUMNS. Then, if I find that there is a column I DO need, I go back to that REMOVE OTHER COLUMNS step, and modify the command by adding the name of the column I need back in. Super easy, super quick.

I completely agree with removing columns that you don't need. But, I think we need to be careful that we don't remove so many columns that we can no longer guarantee uniqueness in the table. When a context transition occurs, the table is iterated and if we have duplicate rows, they will get double (or triple etc.) processed causing very hard to catch (and resolve) bugs.

I have to admit I was a little bit surprised that Darren Gosbell wasn't mentioned as he's the creator and main contributor of DAX Studio. Yes, no doubt that Marco and Alberto (I have huge respect for them) have contributed in some of the coding; Marco has also mentioned a few times that people have mistaken him as its creator and had to clarify that he contributed approx. 5 - 10% of it. So I'm not sure whether that's the case here. Once again, thanks for the awesome contents and keep being awesome!

So I have a question since I am confused. Based on another video as Well I wonder should I use SQL to pre-filter when loading data OR should I Just load all and remove data and columns I don't need using transformations. You pointed out in another video that transformations Will be blocked if you use SQL tot pre-select data. Or is that only the case if you have used select all and not select specific columns? Secondly would it improve speed of In create a query which links all ID's tò eachother in 1 table and can you increment only that table and refresh the lookup tables whenever you need them? Basically is the refresh of a model done on the whole model of specifically to certain tables.

The most of Power BI devs use all columns from source and them doesn't understand why the project runs slow. The best solution is first PREPARE your data source. In SQL Server, create Queries with only columns that you have to use into Power BI. This process is much more faster than others. And, also, you have at PBI all columns that you will use.

One thing I always do is ensure I get rid of datetime fields especially if time is very precise. Set as date or if you need the time extra it into another column. a Datetime has high cardinality but a date and time in sperate fields are low. If I don't need to be so precise I could just have the minute of the day or the hour. I also add any custom columns in M/Powerquery rather than Dax as you can get better compression or if I can use a measure.

Just stumbled across this video - some good tips. Couple of questions though: 1. Unchecking the auto-date/time setting stops me from being able to show a nice hierarchical date slicer (Year->Qtr->Month->Day) - How could I still have one or more of those with the setting disabled? 2. For reducing the number of columns in the dataset, wouldn't it be better to edit the initial source query to only get the columns you need from source? Otherwise, you are telling Power BI to pull in all the columns (and have to handle them all), just to then say "now forget about half the columns I just told you to import"

Hey guys in a cube! I've run into a memory issue with my PBI reports. The dashboard visual is a table (🤦) and the stakeholder wants to add a new measure to the table. The file size is less than 100MB, and I went through these great tips, but when I try to pull in the new measure, I still get an error that there's not enough memory to complete the action. It pulls in fine when I create a new page with less columns in the table. Q: is there a limit to the number of columns PBI can handle in a visual table? I'm currently working on recreating the measures in a specific measure table and out of the data table hoping that will relieve the memory. Am I on the wrong track? Any advice for fixing memory issues?
