Helper IIICross join for a big table
Hello,
I have a table that have 150 million rows and it needs to cross join with a table with 180 rows.
I worte a dax and create a table. It is faster than Power query editor or SQL but it takes one hour to refresh in Power BI Desktop.
Do you have any suggesttion to improve the performance?
Or any other soultion that will have the same result?
Thank you.

Nicki , crossjoin is a costly operation. 150M *180 is a big number.
In file->options and setting -> option under data load, increase cache memory. Also, increase the virtual RAM of the system and try
NickiCache memory is maximum. Thank you for response.
