Hello Comunity,
I add Index column, and when I analyzing performance with DAX Studio, I found that Index column cost 30% of table size,
I need Index column, because I split all rows in my rawdata to several rows.
Is there any way to reduce this size to increase performance?

Having index columns in your model will create high cardinality, better if you could avoid it. One way you can boost your model and calculation performance is to create summary tables and base your measures on them. Also, try and use the aggregation functionality.

@Denis_Slav - You can't really help it. Index columns are all unique row values, so column compression is almost useless. This is also why date tables tend to be large consumers of data model space as well.
